Dec 05, 2018 · The exact character of orbital overlap determines the bond’s strength, angle, length, and elasticity. For example, a diatomic hydrogen molecule (H₂) has the simplest and most stable type of covalent bond; a sigma bond (represented as σ-bond). Sigma bonds form as the result of the direct overlap of two s orbitals. Bond angle 104.5°. There are 2 bonded pairs and 2 lone pairs Lone pairs repel more than bonded pairs. 3. Chemists have developed models for bonding and structure which are used to explain different (ii) Explain why a molecule of NCl3 has this shape and a bond angle of 107°. [3].

A quick explanation of the molecular geometry of NCl3 (Nitrogen trichloride) including a description of the NCl3 bond angles. Looking at the NCl3 Lewis...The Be 2sp orbitals are identical and oriented 180° from one another (i.e. bond lengths will be identical and the molecule linear) The promotion of a Be 2s electron to a 2p orbital to allow sp hybrid orbital formation requires energy. The elongated sp hybrid orbitals have one large lobe which can overlap (bond) with another atom more effectively
The shape of a molecule is determined by its bond angles, the angles made by the lines joining the nuclei of the atoms in the molecule. The bond angles of a molecule, together with the bond lengths (Section 8.8), define the shape and size of the mole-cule. In Figure 9.1, you should be able to see that there are six Cl¬C¬Cl bond angles in CCl. 4 Distortion of Bond Angles. Note that molecules whose central atom A has lone pairs of electrons or double bonds, as well as single bonds, may possess distorted bond angles, as governed by rule 2. Similarly, the operation of the factors that give rise to rules 3 and 4 may also result in distorted bond angles.
