Question

what is this compound called R-C=O-ONa

Answer 1

Hey there,

-COOR group is called ester.
PREFIX = alkoxy carbonyl
SUFFIX = oate

Therefore RCOONa is called-Sodium alkanoate.

Eg-If methyl alkyl group is present, then
CH₃COONa is called Sodium ethanoate.

[THOUGH WE HAVE USED METHYL GROUP, BUT ETHANOATE IS USED BECAUSE ONE CARBON IS ALREADY PRESENT]

PLEASE MARK AS BRAINLIEST IF HELPFUL!!!
