Concept explainers
Interpretation:
The statement which is not true for molecular compounds needs to be identified.
Concept introduction:
Molecular compounds are formed by sharing of electrons between the atoms forming covalent bonds.
Answer to Problem 7STP
C. All atoms have eight valence electrons when they are stable. Eight valence electrons from octet rule but in a few cases there are exceptions.
Example: Aluminium forms compounds where they get stable even with six valence electrons. Hydrogen has 2 electrons in its stable state.
Explanation of Solution
A. Triple bond strength is greater than single bond hence, triple bonds are stronger than single bonds.
B. Covalent bonds are formed when electrons are shared from each other whereas ionic bond is formed between cation and anion after complete transfer of electron from cation to anion.
D. Lewis dot structure represents arrangement of bonds pairs and lone pairs in a covalent compound.

- In natural rubber or polyisoprene, the trans isomer leads to a higher degree of crystallinity and density than the cis isomer of the same polymer, because(a) it is more symmetrical and regular.(b) it is less symmetrical.(c) it is irregular.arrow_forwardMost ceramic materials have low thermal conductivities because:(a) Electron mobility is strongly restricted due to their strong ionic-covalent bonding.(b) False, in general they are excellent thermal conductors (they are used in ovens).(c) Electron mobility is dependent on T and therefore they are poor conductors at high temperatures.(d) Electron mobility is very restricted by secondary bonds.arrow_forwardResistivity and electrical conductivity.(a) In metals, resistivity decreases.(b) In metals, resistivity decreases and conductivity in semiconductors also decreases with increasing temperature.(c) With increasing temperature, resistivity in metals and conductivity in semiconductors also increases.(d) None of the above.arrow_forward
- State the difference between concrete and Portland cement.(a) There are no differences, in concrete the chemical composition is silicates and in cement aluminates.(b) The chemical composition of concrete is based on silicates and in cement aluminates.(c) Concrete is composed of aggregates bound by cement and cement "only" contains different minerals.(d) Cement is aggregates bound by concrete.arrow_forwardAmorphous polymers are usually transparent and semi-crystalline polymers are usually opaque. Correct?(a) No. They are all made up of polymer chains. True if they were monomers.(b) Yes. The arrangement of the chains determines the passage of light.(c) No. It is the other way around.(d) Crystallinity or amorphousness does not affect the transparency or opacity of the material.arrow_forwardThe name ferrites refers to a family of(a) ceramic materials that exhibit ferrimagnetic behavior due to their ionic composition.(b) polymeric materials that exhibit ferrimagnetic behavior due to their ionic composition.(c) concrete-based materials that exhibit ferrimagnetic behavior due to their ionic composition.(d) superconducting materials that exhibit ferrimagnetic behavior due to their ionic composition.arrow_forward
- State the two main factors affecting ion packing in the solid state.(a) Number of covalent bonds and their unsaturation.(b) Mechanical properties and degradation temperature.(c) Number of crystalline phases present and grain size.(d) Electroneutrality and ion size.arrow_forwardThe ceramic materials alumina (Al2O3) and chromium oxide (Cr2O3) form an isomorphic phase diagram. The solubility will be(a) unlimited of one ceramic in the other.(b) very limited depending on the weight % of Al2O3(c) very limited depending on the weight % of Cr2O3(d) partial of one ceramic in the other.arrow_forwardAmong the main characteristics of optical fibers, indicate which of the following is not included:(a) Opacity and Rigidity(b) Flexibility(c) Transparency(d) Low thicknessarrow_forward
- Most ceramic materials have low thermal conductivities because(a) Electron mobility is strongly restricted due to their strong ionic-covalent bonding.(b) False, in general they are excellent thermal conductors (they are used in ovens).(c) Electron mobility is dependent on T and therefore they are poor conductors at high temperatures.(d) Electron mobility is highly restricted by secondary bonds.arrow_forwardSi increases its conductivity when doped with Ga and P.(a) True, because the conduction mechanism is due to electrons and holes generated by Ga and P as the case may be.(b) True, because a completely different compound is generated.(c) False, because when impurities are introduced, the opposite occurs.(d) False, because the conductivity of Si is only determined by the increase in temperature, which must be controlled.arrow_forwardIndicate whether a configuration and a microstate are the same:a) Yesb) No, a microstate encompasses several configurationsc) No, a configuration is the same as a macrostated) No, a configuration encompasses several microstatesarrow_forward
