In silicon tetrachloride (SiCl₄), there are four bond pairs. Each silicon atom forms a covalent bond with a chlorine atom, resulting in the formation of four Si-Cl bonds, which are considered bond pairs. Thus, SiCl₄ has a total of four bond pairs.

A tetrahedral molecule will have a 109.5 degree bond angle.
In phosphine (PH3), there are three lone pairs and three bonding pairs.
SiF4 is a better Lewis acid than SiCl4 primarily due to the stronger electronegativity of fluorine compared to chlorine. The high electronegativity of fluorine creates a more polarized bond, making the silicon atom in SiF4 more electron-deficient and thus more willing to accept electron pairs. Additionally, the smaller size of fluoride ions leads to less steric hindrance compared to chloride ions, enhancing the Lewis acidity of SiF4. This combination of factors makes SiF4 a stronger Lewis acid than SiCl4.
Sharing two pairs makes a double bond. Sharing three pairs makes a triple bond.
In SiCl4, silicon has no lone pairs because it forms four bonds with chlorine atoms, satisfying its octet rule.

CCl4 has a covalent bond, where carbon and chlorine atoms share electron pairs to form a stable molecule. This results in a tetrahedral geometry where each carbon atom is surrounded by four chlorine atoms.
Yes, SiCl4 forms ionic bonds. Silicon (Si) is a metalloid that can exhibit both covalent and ionic bonding. In SiCl4, silicon forms ionic bonds with chlorine (Cl) due to the large electronegativity difference between the two elements.

BCl3 has 3 bond pairs. Each chlorine atom forms a single covalent bond with the central boron atom.
There are a infinitely growing number of bond pairs between atoms.
A tetrahedral molecule will have a 109.5 degree bond angle.
Silicon tetrachloride, with formula SiCl4
The bond order is the number of shared electron pairs between two atoms in a covalent bond. A single bond has a bond order of 1 (one shared pair), a double bond has a bond order of 2 (two shared pairs), and a triple bond has a bond order of 3 (three shared pairs).
