Answer 2

Hey dear,

● Allyl alcohol to propenal -
Allyl alcohol has structural formula CH2=CH-CH2-OH.

Allyl alcohol on addition ozone gives an intermediate which on further treatment with zinc/water gives propenal & methanal.

CH2=CH-CH2-OH + O3 --> CH2-O3-CH-CH2-OH
CH2-O3-CH-CH2-OH + H2O --> CH3-CH2-CHO + HCHO


* Alternatively, allyl alcohol on treatment with pyridinium chlorochromate also gives propenal.

Hope this helps you.
