Question

17) Alkenes react with 98% H2SO4 and forms -
a) Alkynes
b) Alkanes c) Aldehydes
d) Alcohols​

Answer 1

Answer:

alcohol

Explanation:

alkene is concentrated sulphuric acid to from alkyl hydrogen sulphate, which on heating with water gives alcohol

Answer 2

ALKENES REACTION WITH CONCENTRATED SULPHURIC ACID

Alkenes react with 98% H2SO4 and forms alkyl hydrogen sulphates which on heating with water results in the formation of (D) alcohols.

GETTING TO KNOW MORE ABOUT FUNCTIONAL GROUP NAMELY ALCOHOL:

* In organic  chemistry, alcohols are a few of the maximum large compounds. They can be produced from and modified right into a huge variety of chemicals.

* The hydroxy purposeful organization (-OH) is hooked up to a carbon atom of an alkyl or substituted alkyl organization in alcohols. The hydroxyl organization, –OH, is the purposeful organization of an alcohol.

* This organization, not like the alkyl halides, possesses  reactive covalent bonds: the C–O and the O–H bonds. Oxygen has a appreciably better electronegativity than carbon and hydrogen.

*  As a result, the covalent bonds of this purposeful organization are polarised, ensuing in an electron-wealthy oxygen and electrophilic carbon and hydrogen.
