Question

The formula of propionic acid is C_2H_5COOH. The conjugate base of propionic acid is called , and its formula is .

Answer 1

we know that

if we remove H+ from an acid , we get its conjugate base

also

if we add H+ to a base , we get its conjugate acid

now

given propionic acid , C2H5COOH

to get its conjugate base

remove H+

we get C2H5COO-

so

the formula of its conjugate bae is C2H5C00-

and

it is called propionate

so

the answer is

propionate , C2H5COO-
