Question

Vinyl carbinol is:
A. \[HO - C{H_2} - CH = C{H_2}\]
B. \[ C{H_3} - C(OH) = C{H_2} \]
C. \[C{H_3} - CH = CH - OH\]
D. \[C{H_3} - C(C{H_2}OH) = C{H_2}\]

Answer 1

Hint:Initially you must be sure that the compound named vinyl carbinol is an alcohol. There is a simple method to find out the correct option. Just check whether the group has branches or not and you will get your answers easily.

Complete answer:The structure of a vinyl group is equivalent to the molecular group when one hydrogen atom is removed from an ethene molecule. Therefore, it is also known as an ethenyl group. It contains two sp2 hybridized carbon atoms and three hydrogen atoms. The removed hydrogen atom can be replaced by any group of molecules, and it is denoted as –R.Now for the case of allyl group When one hydrogen atom is removed from the third carbon atom of a propane molecule, it is equivalent to an allyl group. It contains two sp2 hybridized carbon atoms and one sp3 hybridized carbon atom. In other words, it is a methylene bridge (-CH2-) attached to a vinyl group (-CH=CH2).
Now examining this \[HO - C{H_2} - CH = C{H_2}\]

Hence the option A is the correct option.

Note:Vinyl carbinol also known as 2-propanol. It is a colourless liquid. It has pungent odour which is used in making resins. Its plasticisers are highly irritating to mucous membranes and readily absorbed, causing depression and coma. It boils at 96.9°C and its density is 852 kg/m3 .It mixes in any proportion with water, alcohol, or ether. Which means it is easily soluble in all the mediums. Vinyl alcohol is obtained by the hydrolysis of allyl chloride. It is a kind of primary carbinol.
