The addition of HBr to an alkene follows Markovnikov's rule, leading to the formation of the more stable alkyl bromide as the major product.

The reaction is an electrophilic aromatic substitution, resulting in the formation of bromobenzene as the major product.

The major product is 2-methylpropan-2-ol due to Markovnikov's rule, where water adds to the more substituted carbon.

The dehydration of an alcohol typically results in the formation of an alkene.

The hydrogenation of 1-butyne with H2 in the presence of a catalyst results in the formation of butane.

The addition of H2 across an alkene occurs via syn addition, resulting in both hydrogens adding to the same side of the double bond.

S_N2 reactions result in inversion of configuration at the carbon center where substitution occurs.

The reaction between an alcohol and a carboxylic acid forms an ester through a condensation reaction.

Tertiary alkyl halides favor the S_N1 mechanism due to steric hindrance, leading to the formation of a carbocation intermediate.

Tertiary alkyl halides favor the S_N1 mechanism due to steric hindrance and the stability of the carbocation.

1-bromopropane undergoes S_N2 reactions most readily due to less steric hindrance compared to secondary and tertiary halides.
