How many alcohols from the following set will yield geometric isomers on dehydration? Propan-2-ol, 2-methylpropan-1-ol, pentan-2-ol, ethanol, propan-1-ol, 2-methylpropan-2-ol, butan-1-ol, butan-2-ol, hexan-3-ol

Correct answer

3

Step-by-step solution

pentan-2-ol, butan-2-ol and hexan-3-ol yield geometrical isomers on dehydration. i. Pentan-2-ol: ii. butan-2-ol → cis -but-2-ene + trans- but-2-ene iii. Hexan-3-ol:
