Question

The dehydration yield of cyclohexanol to cyclohexene is $75$. What would be the yield if $100g$ of cyclohexanol is dehydrated?

• A. $61.7g$
• B. $16.5g$
• C. $6.15g$
• D. $615g$

Answer 1

The correct option is A $61.7g$

Molar mass (cyclohexanol) $=100g/mole$ Molar mass (cyclohexene) $=82g/mole$
So $100g$ cyclohexanol 'should' give $82g.$
But only $75$ yield

So $0.75\times 82=61.5$ g is actual yield or is similar to $61.7$ g
