What is the major elimination product in the reaction of 1-bromobutane with potassium tert-butoxide in tert-butanol? cis-2-butene butanol trans-2-butene 1-butene?

Here we have to get the major eleminated product in the reaction of 1-bromobutane with potassium tert-butoxide in tert-butanol.

In the reaction of 1-bromobutane with potassium tert-butoxide in tert-butanol gives 1-butene.

Here,  in the reaction of 1-bromobutane with potassium tert-butoxide, elemination reaction takes place.

Potassium tert-butoxide is bulky in size, it eliminates hydrogen from β-position and β-elimination reaction takes place. Hence, the product formed is 1-butene.

the answer would be a
