Which of the species with octets in Question 31 are dipoles?

Interpretation Introduction

(a)

Interpretation:

The identity of SO2 from the context of dipoles needs to be established.

Concept introduction:

  • Chemical bonds can be broadly classified as ionic (formed by complete transfer of electrons) or covalent (formed by mutual sharing of electrons)
  • Covalent bonds can be further classified as polar, if there is an unequal distribution of electrons or non-polar in case of symmetrical distribution of electrons.
  • Polar bonds have positive and negative ends called dipoles. These are absent in non-polar bonds.

Explanation of Solution

The most stable Lewis structure for SO2 is as follows:

The central S atom is bonded to 2 O atoms; in addition there is a lone pair on the S atom...

Interpretation Introduction

(b)

Interpretation:

The identity of BeF2 from the context of dipoles needs to be established.

Concept introduction:

  • Chemical bonds can be broadly classified as ionic (formed by complete transfer of electrons) or covalent (formed by mutual sharing of electrons)
  • Covalent bonds can be further classified as polar, if there is an unequal distribution of electrons or non-polar in case of symmetrical distribution of electrons.
  • Polar bonds have positive and negative ends called dipoles. These are absent in non-polar bonds.
Interpretation Introduction

(c)

Interpretation:

The identity of SeCl4 from the context of dipoles needs to be established.

Concept introduction:

  • Chemical bonds can be broadly classified as ionic (formed by complete transfer of electrons) or covalent (formed by mutual sharing of electrons)
  • Covalent bonds can be further classified as polar, if there is an unequal distribution of electrons or non-polar in case of symmetrical distribution of electrons.
  • Polar bonds have positive and negative ends called dipoles. These are absent in non-polar bonds.
Interpretation Introduction

(c)

Interpretation:

The identity of PCl5 from the context of dipoles needs to be established.

Concept introduction:

  • Chemical bonds can be broadly classified as ionic (formed by complete transfer of electrons) or covalent (formed by mutual sharing of electrons)
  • Covalent bonds can be further classified as polar, if there is an unequal distribution of electrons or non-polar in case of symmetrical distribution of electrons.
  • Polar bonds have positive and negative ends called dipoles. These are absent in non-polar bonds.
