common alkene addition reactions that follow Markovnikov's Rule are as follows:$$ Hydrohalogenation adds HX as H and X $($where X $=$ F$.$ Cl$.$ or Br$)$ Halogenation adds X$$ as X and X $($where X $=$ Cl or Br$)$ Hydration adds H$$O as H and OH$$ Hydrogenation adds H$$ as H and HFor each reaction described below, draw the structures of the following alkenes AND their expected products

A$.2-$methyl$-1-$pentene $+$ HBr $($hydrohalogenation$)$B$.2-$butene $+$ Cl$2($halogenation$)$C$.1-$butene $+$ H$$O $($hydration$)$D$.1-$methyl$-1-$cyclohexene$+$ H$($hydrogenation$)$
