A1 - Covalent Bonding Flashcards
1
Q
What is the definition of a dative covalent bond?
A
A dative bond is a covalent bond where only one of the bonded atoms donates both electrons being shared.
2
Q
What happens during sigma and pi bonds?
A
Orbitals hybridise in bonding.
3
Q
Describe sigma bonds:
A
Single bonds, formed by a direct overlap of orbitals in the middle of 2 bonding atoms.
4
Q
What is the definition of a dative bond?
A
A covalent bond where only one of the bonded atoms donates both electrons being shared. The shared electron pair was originally a lone pair of electrons on one of the bonded atoms.
5
Q
What is average bond enthalpy?
A
It serves as a measure of covalent bond strength
6
Q
Which is stronger, sigma or pi bonds? Why?
A
Sigma bonds because the orbitals overlap more.
