Which of the products will be major product in the reaction given below? Explain.

CH₃CH = CH₂ + HI → CH₃CH₂CH₂ I + CH₃CHICH₃

                                         (A)                         (B)

To measure light intensity we use

A 0.8 m long solenoid has 800 turns and has a field density of 2.52 × 10^–3 T at its centre. What is current in the wire?

Consider the following reaction sequence

Product B is

Major product of the given reaction is

(CH₃)₃CBr + CH₃–CH₂–ONa → product

Chloroform on reaction with O₂ in presence of light gives
