Answer» `CH_2=CH-CHO overset(HCl(g)(-10^@C))to undersetunderset(CL)(\|)CH_2-CH_2-CHO` `CH_2=CH-COOH overset(H_2O // H_2SO_4)to undersetunderset(OH)(\|)CH_2-CH_2-COOH` `CH_3-oversetoverset(CH_3)(\|)C=CH-undersetunderset(O)(\|\|)C-CH_3overset(CH_3OH//H_2SO_4)to CH_3-oversetoverset(CH_3)(\|)CH-undersetunderset(OCH_3)(\|)CH-undersetunderset(O)(\|\|)C-CH_3` `CH_3-CH=CH-OCH_3overset(CH_3OH//H^+)toCH_3-CH_2-undersetunderset(OCH_3)(\|)CH-OCH_3` Solution :The more STABLE CARBOCATION of alkene gives the major product in ELECTROPHILIC addition reactions.
