: The molecular formula of chlorophyll a is C55 text H72 text O5N4 text Mg and that of chlorophyll b is C55 text H70 text textO6 text N4 text Mg . In chlorophyll b there is a -CHO group instead of a -CH3 group at the 3rd C atom in II pyrrol ring.

Q. The formula for chlorophyll a is

$C_{55} H_{70} O_{6} N_{4} M g$

$C_{55} H_{72} O_{5} N_{4} M g$

$C_{25} H_{72} O_{5} N_{4} M g$

$C_{22} H_{72} O_{5} N_{4} M g$

: The molecular formula of chlorophyll a is $C_{55} H_{72} O_{5} N_{4} M g$ and that of chlorophyll b is $C_{55} H_{70} O_{6} N_{4} M g$ . In chlorophyll b there is a $- C H O$ group instead of a $- C H_{3}$ group at the 3rd C atom in II pyrrol ring.
