Polarization in acrolein as:...

Polarization in acrolein as:

`overset (-delta) CH_2 = CH - overset (+delta)C = O`

`overset (-delta) CH_2 = CH - CH = overset (+delta) O`

`overset (-delta)CH_2 = overset(+delta)CH - CH = O`

`overset (-delta)CH_2 = CH - CH = overset (-delta)O`

Text Solution

Verified by Experts

The correct Answer is:

(d) `O` atom is more `EN` than `C` atom, so it acquires `(-delta)` charge and `C` atom acquires `(+ delta)` charge which is transferred to the last `C` atom.

Polarisation of electrons in acrolein cannot be written as :

`overset(delta-)(C)H_(2)=CH-overset(delta+)(C)=O`

`overset(delta-)(C)H_(2)=CH-CH=overset(delta+)(O)`

`overset(delta-)(C)H_(2)=overset(delta+)(C)H-CH=O`

`overset(delta+)(C)H_(2)=CH-CH=overset(delta-)(O)`

Glycerol can be converted to acrolein by dehydration in presence of :

Conc. `H_(2)SO_(4)`

`KHSO_(4)`

`CaCl_(2)`
