Question

The compound acetaldehyde most likely contains the functional group shown below:

-C-
downwards equal sign
O
true or false.

Answer 1

True

Further explanation

Aldehydes are alkane-derived compounds containing the functional group (-CO-) located at the end of the parent carbon chain

The general structure is R-CHO with the molecular formula CnH2nO

Naming is generally the same as the alkane by replacing the suffix with -al

Acetaldehyde(ethanal) is an aldehyde which has 2 C atoms with formula

`\boxed{\bold{C_2H_4O}}`

The bond between the C atom and the O atom is a double bond

So the C atom has a single bond with H and alkyl and double bonds with O

R - C - H

O
