1
(a) sp hybridisation: one s orbital mixes with one p orbital, forming two equivalent sp hybrid orbitals. Types of Hybridisation linear 180 two sp hybrid orbitals 50% s character 50% p character Eg. BeC l 2

2
(Linear arrangement) 2s 2p x 2p y 2p z unhybridised 2p y 2p z sp hybridisation Hybrid orbital: unequal size lobes unhybridised orbital: lobes of equal size sp Hybridisation

3
(b) sp 2 hybridisation: one s orbital mixes with two p orbitals forming three equivalent sp 2 hybrid orbitals Types of Hybridisation trigonal planar 120 three sp 2 hybrid orbitals 33.3% s character 66.7% p character Eg. BC l 3

4
(Linear arrangement) 2s 2p x 2p y 2p z sp 2 hybridisation sp 2 Hybridisation unhybridised 2p z Trigonal planar arrangement unhybridised orbital: for π bond formation or left vacant Three sp 2 hybrid orbitals

5
(c) sp 3 hybridisation: one s orbital mixes with three p orbitals forming four equivalent sp 3 hybrid orbitals. Types of Hybridisation tetrahedral four sp 3 hybrid orbitals 25% s character 75% p character Eg. CH 4

6
2s 2p x 2p y 2p z sp 3 hybridisation sp 3 Hybridisation Tetrahedral arrangement Four sp 3 hybrid orbitals
