Butan-2-ol can be dehydrated to either but-1-ene or but-2-ene and since there is restricted rotation in but-2-ene there is a chance that either cis or trans will be formed at the end of dehydration ,

Why answer cant be C?

Because the products of dehydration of that molecule is 2-methylbut-1-ene and 2-methlybut-2-ene only 2 and yes there is a double bond but there can't be cis trans as there is no restricted rotation Around the double bond between the carbon atoms because In 2-methyl but-1-ene the carbon atom at position number 1 which is involved in the double bond have same atoms (hydrogen atoms ) and in 2-methyl but-2-end the carbon atom at position number 2 which is involved in the double bond have same group of atoms which is the methyl groups

For CIE A level Chem, is there a simple way to remember when to use reflux when not to use? The mark schemes aren't very consistent...
