Meso "2,3" -dibromo butane is treated with "Kl" in acetone The product formed is
(A) Cis but-2-ene
(B) Trans but-2-ene
(C) But-1-ene
(D) Both (A) and (b) "]

What will happen when Br_2//C Cl_4 react with (a) cis But-2-ene (b) trans But-2-ene.

When cis-but-2-ene is treated with Br_(2) in "CCl"_(4) medium the product formed will be

During debromination of meso-dibromobutane, the major compound formed is n-butane but-1-ene cis-but-2-ene trans-but-2-ene

The product formed when but-1-ene is subjected to HBr in the presence of peroxide is

The addition of Br_2 to ( E)-but-2-ene gives

Which of the following can show geometrical isomerism? (i) Propene (ii) But-1-ene (iii) But-2-ene (iv) Pent-2-ene

When cis-2,3-dibromopent-2-ene is hydrogenated with H_2//Pt , The product is : (i) Meso-2,3 -Dibromopentane (ii) (+)2,3 -Dibromopentane (iii) (-)2,3 -Dibromopentane (iv) (+-)2,3 -Dibromopentane

A compound (A) reacts with thionylchloride to give a compound (B). (B) reacts with magnesium to form a Grignard reagent which is treated with acetone and the product is hydrolysed to give 2-methyl butan-2-ol. What are the structural formulae of (A) and (B) ?

Give a chemical test to distinguise between but -1- ene and but -2- ene.

Asssertion : 2-iodobutane on reacting with sodium ehtoxide. In ethanol gives but -2-ene as the major prodcut. Reason : But-2-ene is more stable than but-1-ene.
