(a)
Interpretation: The geometrical isomers of the given compounds are to be determined.
Concept introduction: The geometrical isomer or cis-trans isomers are the isomers with different spatial arrangements of the groups attached to the central atom.
In cis isomer, two of the liked groups are placed adjacent to each other. While in trans isomers, the two liked groups are placed opposite to each other.
To determine: The geometrical isomers of

- CaTiO3 has a perovskite structure. Calculate the packing factor.Data: ionic radii Co+2 = 0.106 nm, Ti+4 = 0.064 nm, O-2 = 0.132 nm; lattice constant is a = 2(rTi4+ + rO-2).(a) 0.581(b) -0.581(c) 0.254(d) -0.254arrow_forwardIn the initial linear section of the stress-strain curve of a metal or alloy. Explain from the point of view of atomic structure?(a) No, the atomic level properties of the material can never be related to the linear section.(b) The elastic zone is influenced by the strength of the bonds between atoms.(c) The stronger the bond, the less rigid and the lower the Young's Modulus of the material tested.(d) The stronger the bond, the less stress is necessary to apply to the material to deform it elastically.arrow_forwardThe degree of polymerization of polytetrafluoroethylene (Teflon) is 7500 (mers/mol). If all polymer chains have equal length, state the molecular weight of the polymer and the total number of chains in 1000 g of the polymer(a) 50 000 g/mol; 0.03·1020 chains(b) 100 000 g/mol; 1.03·1020 chains(c) 750 000 g/mol; 8.03·1020 chainsarrow_forward
- 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
