\(a)\ CH_3-CH=CH-CH_3 + H_2 \xrightarrow{t^o,Ni} CH_3-CH_2-CH_2-CH_3\\ b)\ CH_2=CH-CH_3 + Br_2 \to CH_2Br-CHBr-CH_3\\ c)\ CH_2=C(CH_3)-CH_3 + HBr \to CH_3-CBr(CH_3)-CH_3\\ d)\ CH_2=CH-CH_2-CH_3 + H_2O \xrightarrow{H^+,t^o} CH_3-CH(OH)-CH_2-CH_3\\ e)\ CH_3-CH=CH-CH_3 + HBr \to CH_3-CH_2-CHBr-CH_3\\ f)\ C_2H_4 + 3O_2 \xrightarrow{t^o} 2CO_2 + 2H_2O\\ g)\ nCH_2=CH_2 \xrightarrow{t^o,p,xt} (-CH_2-CH_2-)_n\\ h)\ nCH_2=CH-CH_3 \xrightarrow{t^o,p,xt} (-CH_2-CH(CH_3)-)_n\)
