Dopamine works as an important neurotransmitter in brain. Its IUPAC name is 4-(2-aminoethyl)benzene-1,2-diol and its structure is 51g of dopamine will not contain as may carbon atom as there are total C-atoms in :

A

`(800)/(3)g CaCO_(3)`

B

`80g CH_(3)COOH`

C

`(104)/(3)g C_(6)H_(6)`

D

`60g C_(6)H_(12)O_(6)`

Text Solution

Verified by Experts

The correct Answer is:
B

dopamine works as ……………..
`(Mol.wt.)_(dopa) = 153g mol^(-1)`
`w = 51g`
`n_(dopa)= (51)/(153) = (1)/(3)mol, (n_(C ))_(dopa) = (1)/(3)xx8 = (8)/(3)mol`
`CaCO_(2): n = (800)/(3xx100)=(8)/(3), n_(c )= (8)/(3)`
`CH_(3)COOH : n = (80)/(60) = (4)/(3), n_(c ) = (8)/(3)`
`C_(6)H_(6) : n = (104)/(3xx78) = (4)/(9), n_(c ) = (8)/(3)`
`C_(6)H_(12)O_(6) : n = (60)/(180) = (1)/(3), n_(c ) = 2`
