Question

Name the first member of ketone family write its molecular formula structural formula electron dot structure and IUPAC name

Answer 1

The first member of ketone family is acetone or propanone.
Molecular formula — C3H6O or CH3-CO-CH3 or (CH3)2CO
IUPAC Name — Propan-2-one

Answer 2

The first member of the ketone family is acetone or propanone.

Molecular formula is

$C_3H_6O$

or

$CH_3-CO-CH_3$

or

$(CH_3)_2CO$

IUPAC Name is Propan-2-one.

The structure of 2-propanone or propanone is shown above .

Note: Here, methanone or ethanone cannot exist as they cannot have a secondary carbonyl group, thus propanone is the first in the ketone series.
