In the following reactions, (a) {\CH}_3- {\C^{|↖{ \CH_3}}H}- {\C_{|↙{ \OH}}H}- {\CH}_3\stackrel{H^{+}{────▶}}\A↙({\text{Major product}})+\B↙({\text{Minor product}})(b) A\stackrel{\HBr,\dark}{─\xrightarrow[\text{In absence of peroxide]{}} C↙({\text{Major product}})+D↙({\text{Minor product}}) the major products (A) and (C) are respectively :

Correct Answer is : CH3−CH3|C=CH−CH3 and CH3−CH3|C|Br

{\CH}_2= {\C^{|↖{ \CH_3}}}- {\CH}_2- {\CH}_3 and {\C_{|↙{ \Br}}H_2}- {\C^{|↖{ \CH_3}}H}- {\CH}_2- {\CH}_3

CH_3-C^{|↖{ \CH_3}}=CH-CH_3 and CH_3-C^{|↖{ \CH_3}}_{|↙{ \Br}}

{\CH}_3- {\C^{|↖{ \CH_3}}}= {\CH}- {\CH}_3 and CH_3-C^{|↖{ \CH_3}

CH_2=C^{|↖{ \CH_3}}-CH_2-CH_3 and CH_3-C^{|↖{ \CH_3}}_{|↙{ \Br}}-CH_2-CH_3CH_3-C^{|↖{CH_3}}_{|↙{ \Br}}
