(b)
Interpretation:
The contributing structures for pyridine have to be drawn.
Concept Introduction:
Contributing structures:
The double bonds of an aromatic compound shift back and forth very rapidly which is known as delocalization. The resulted forms or structures cannot be separated and stay in equilibrium with charge separation. Those structures are known as contributing structuresof that compound.

- (b) Draw structural formulas of at least two alkynes of each molecular formula.(1) C6H10arrow_forwardTRUE OR FALSE (a) Both ethylene and acetylene are planar molecules. (b) An alkene in which each carbon of the double bond has two different groups bonded to it will show cis-trans isomerism. (c) Cis-trans isomers have the same molecular formula but a different connectivity of their atoms. (d) Cis-2-butene and trans -2-butene can be interconverted by rotation about the carbon–carbon double bond. (e) Cis-trans isomerism is possible only among appropriately substituted alkenes. (f) Both 2-hexene and 3-hexene can exist as pairs of cis-trans isomers. (g) Cyclohexene can exist as a pair of cis-trans isomers. (h) 1-Chloropropene can exist as a pair of cis-trans isomers.arrow_forward(b) NABH, CH3 COCH,CH3 CH3CH2OH (c)arrow_forward
