Question 2

Geometry and bond angle of sp2

Answer 2

120 trigonal planar

Question 3

Geometry and bond angle of sp

Answer 3

Linear 180

Question 4

Bond become shorter as %s character increases since s orbital are spherical and electrons are held closer to the nucleus

Answer 4

True

Question 5

Answer 5

Bp
Type of imf
Physical properties
Nomenclature
Chemical reactivity

Question 6

The three subgroup of aliphatic hydrocarbons

Answer 6

Alkanes alkenes and alkynes

Question 7

C-Z bonds includes __,____,____ where the electronegative atom Z creates a polar bomd making C electron poor. Thus this undergo reaction with nucleophilic specie

Answer 7

Alcohol ether amine alkyl halide

Question 8

Contains the carbonyl group C=O where C is surrounded by three groups making it sp2 hybridized and trigonal planar. The C=ao is polar where C is electron poor thus aldehydes and ketoned undergo nucleophilic addition reaction

Answer 8

Carbonyl compounds

Question 9

Are compounds that contain -COOH which are very polar compounds and because O-H bond, they exhibit hydrogen bonding. Thus this compounds have higher bpiling points and melting points

Answer 9

Carboxylic acid

Answer 10

Carboxylic
Amide
Ester
Acid anhydride
Acid halide
