1.	An alcohol (a) on dehydration gives (b), which on Ozonolysis gives acetone and formaldehyde. (b) decolourises alkaline KMnO_4 solution but (a) does not. (a) and (b) are respectively:
Answer» `CH_3CH_2CH_2CH_2OH and CH_3CH_2CH=CH_2` `CH_3CH_2-overset(OH)overset(\|)CH-CH_3 and CH_3-CH = CH-CH_3` `(CH_3)_3 C - OH and (CH_3)_2 C = CH_2` `CH_3 - CH_2 - overset(OH)overset(\|)CH-CH_3 and (CH_3)_2C = CH_2 ` SOLUTION :`underset((A))((CH_3)_3C-OH) underset(-H_2O)to underset((B))(CH_3 - underset(CH_3)underset(\|)C = CH_2)`, `CH_3 - underset(CH_3)underset(\|)C = CH_2 overset(O_3)to underset(CH_3)underset(\|)CH_3 - C = O + HCHO`
