Question

why CHO in salicylaldehyde at ortho position?? and not on para..pls detail it!!​

Answer 1

Answer:

this is due to ortho effect.

Reimer Tiemann Reaction gives both ortho and para products. but ortho is major product.

Answer 2

Answer:

Explanation:

Salicylaldehyde forms intramolecular hydrogen bonding and its para isomer forms intermolecular hydrogen bonding. The effect of acidity due to intermolecular hydrogen bonding is lesser than the effect of hydrogen bonding due to intramolecular hydrogen bonding. This is because intermolecular hydrogen bonds can be broken easily as they are between two molecules and the molecules are in thermal motion.
