The major product formed in the following reaction is:

Correct option(s) for the following sequence of reactions is(are):

For the following reaction scheme, percentage yields are given along the arrow:

\( x \; \text{g} \) and \( y \; \text{g} \) are mass of \( R \) and \( U \), respectively.
(Use: Molar mass (in \( \text{g mol}^{-1} \)) of \( \mathrm{H} \), \( \mathrm{C} \) and \( \mathrm{O} \) as \( 1 \), \( 12 \) and \( 16 \), respectively)
The value of \( x \) is ____.

The amount of energy required to break a bond is same as the amount of energy released when the same bond is formed. In gaseous state, the energy required for homolytic cleavage of a bond is called Bond Dissociation Energy (BDE) or Bond Strength. BDE is affected by s-character of the bond and the stability of the radicals formed. Shorter bonds are typically stronger bonds. BDEs for some bonds are given below:

Correct match of the C–H bonds (shown in bold) in Column J with their BDE in column K is:
