Concept explainers
(a)
Interpretation:
The formula of the coordination compound formed by Cu+ with NH3 needs to be determined.
Concept introduction:
Coordination compounds are those in which a transition metal atom is bonded to a ligand which can be neutral, cationic or anionic. The
(b)
Interpretation:
The formula of the coordination compound formed by Pt2+ with oxalate ion needs to be determined.
Concept introduction:
Coordination compounds are those in which a transition metal atom is bonded to a ligand which can be neutral, cationic or anionic. The transition metal element is enclosed within a bracket and a charge is present on the ion to balance the charge present on the ligands. The total charge present on any complex ion is equal to the sum of the oxidation number of the central metal atom and the total charges of the ligand present in it.
(c)
Interpretation:
The formula of the coordination compound formed by Cd2+ with H2 O needs to be determined.

- Speaking of composite materials, indicate the correct option:(A). Composite materials can only be: metal-polymer or polymer-polymer.(B). Composite materials can be made up of particles, but not fibers or sheets.(C). When the reinforcing particles are uniformly distributed in a composite material, there may be a greater tendency for it to have isotropic properties.(D). None of the above is correct.arrow_forwardIf we are talking about viscoelastic modulus or viscoelastic relaxation modulus in polymers, indicate the correct option.(A). It reports the variation of elastic behavior as a function of time.(B). It is only useful for defining its glass transition temperature.(C). It only allows us to define the polymer degradation temperature.(D). Neither option is correct.arrow_forwardWhen natural light falls perpendicularly on a material A, it has a reflectivity of 0.813%. Indicate the value of the refractive index.arrow_forward
- In piezoelectricity and piezoelectric ceramics, one of the following options is false:(A). Piezoelectricity allows an electrical signal to be transformed into a mechanical one.(B). PbZrO3 is a well-known piezoelectric ceramic.(C). Piezoelectricity and ferroelectricity in general have no relationship.(D). One of the applications of piezoelectricity is sonar.arrow_forward(30 MARKS) Give the major product(s ) formed including relevant stereochemistry or the complete reaction conditions for the following reactions.
