(a) 2 HCOOH
CHO
|
(b)CHO
H
(c) 2 C = O
H
(d) 2 CO₂

Answer 1

H₂COH · CH₂OH on heating with periodic acid gives formaldehyde

-The formula of periodic acid is HIO4

-It is a mild oxidising agent

- So it oxidises alcohols into aldehydes with the removal of water molecule

-  When ethylene glycol is heated with it, then formaldehyde is formed as:  H₂COH · CH₂OH + HIO4 ---> 2 HCHO

- So the correct answer is (c)

Answer 2

see the attached pic and so option c is correct
