Respuesta :

Answer:

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

The statements; "Two sigma bonds comprise a double bond" and "A triple bond consists of one pi bond and two sigma bonds" are false statements.

In chemistry, a bond is formed by the overlap of atomic orbitals. The overlap occurs between orbitals of appropriate energy. A sigma bond occurs due to end to end overlap of orbitals while a pi bond is formed by side by side overlap of orbitals.

The following are true concerning the formation of bonds;

  • Bonds formed from atomic s orbitals are always sigma bonds.
  • A pi bond restricts rotation about the sigma-bond axis.
  • A pi bond consists of two pairs of electrons.
  • End-to-end overlap results in a bond that has electron density along the bond axis.
