Answer:
Explanation:
a ) Benzoic acid is formed . In any alkyl benzene derivative , potassium permanganate reacts to form carboxylic acid . It oxidises side chains to carboxylic acid .
C₆H₅CH₃ + 0 = C₆H₅COOH + H₂O
O is provided by KMnO₄
b ) In this reaction isophthalic acid is formed .
C₆H₄(CH₃)₂ +O = C₆H₄(COOH)₂
c)
4-Propyl-3-t-butyltoluene
In this oxidation , three side chains of ring are 1 ) 1-methyl 2 ) 3- butyl 3 ) 4 propyl .
The methyl and 4 - propyl groups are oxidised to di- carboxylic acid and 3 butyl group remains intact ( unoxidised )
Explanation:
The kinetic energy of an object is given by :

1. Mass, m = 5 kg
Speed, v = 2 m/s

2. Mass, m = 71 kg
Speed, v = 1 m/s

3. Mass, m = 71 kg
Speed, v = 5 m/s

4. Mass, m = 1816 kg
Speed, v = 25 m/s

That specific kind is called gas.
When you put water in a freezing temprature it becomes solid.
When you boil water it becomes gas
