Hebert · Answer 1

1) False

2) False

3) True

4) True

5) False

Explanation:

1. Two sigma bonds comprise a double bond: False

Two sigma bonds are not possible between two atoms. There will always be one pi bond or two bonds with one sigma bond

2. A triple bond consists of one pi bond and two sigma bonds.

Two sigma bonds are not possible between two atoms. There will always be one pi bond or two bonds with one sigma bond

3. Bonds formed from atomic s orbitals are always sigma bonds. True

There is always an head to head overlapping possible with s orbital

4. A pi bond restricts rotation about the sigma-bond axis.

True.

5. A pi bond consists of two pairs of electrons.

False

Each bond can have one pair of electrons
