Explanation:
Tollens test is carried out to perceive difference between aldehydes and ketones on the basis of their capability to oxidized easily.
when Tollens react with aldehyde (heptanal) , a silver mirror is form on inner side of container.
The reaction between tollens and heptanal is given as
![CH_3 CH_2 CH_2 CH_2 CH_2 CH_2 CHO + 2[Ag(NH_3)_2]+ 3 H_2 O](https://tex.z-dn.net/?f=CH_3%20CH_2%20CH_2%20CH_2%20CH_2%20CH_2%20CHO%20%2B%202%5BAg%28NH_3%29_2%5D%2B%203%20H_2%20O)
=
