Question

which have higher boiling point P salicylaldehyde or O salicylaldehyde
​

Answer 1

Answer:

o salicylaldehyde

Explanation:

When phenol reacts with chloroform in the presence of aqueous NaOH at 340 K temperature followed by hydrolysis yields 2−hydroxybenzaldehyde also called salicylaldehyde.

So, o-salicylaldehyde is a major product. Thus product P is o-salicylaldehyde.

Thus product Q will be p-salicylaldehyde.

The melting point of the para-product is greater than the o-product.
