Indicate whether each of the following statement is true CT

Indicate whether each of the following statement is true CT) or false (F). Briefly explain 1- Compound A is non-polar but compound B is polar Ci 2- Structure A contributes the most to the resonance hybrid. 3- An inductive donor effect strengthens a base. 4. For a given compound, staggered conformations are more stable than eclipsed conformations.

Solution

1. FALSE (Compound A is polar because it cis isomers and compound B is non polar because it is trans isomer.)

2. FALSE (The carboxylate ion is hybrid of two equivalent structures whereas carboxylic acid is hybrid of non equivalent structures)

3. TRUE ( You can determine relative basic strength for amines by considering the inductive effect.+ Inductive effect [ + I effect ] is caused by electron releasing groups.)

4. TRUE (A staggered conformer is more stable than an eclipsed conformer as the latter involves unfavourable energy interactions between atoms.)
