Strongest bond is
- A$C-C$
- B$C-H$
- ✓$C-N$
- D$C-O$
✓
Answer
Correct option: C.
$C-N$
c
Multiple bonds have more bond energy so $C \equiv N$ will be the strongest
Multiple bonds have more bond energy so $C \equiv N$ will be the strongest

Given below are two statements: One is labelled as Assertion $A$ and the other is labelled as Reason $R$:
→Assertion $A$: Alcohols react both as nucleophiles and electrophiles.
Reason $R$: Alcohols react with active metals such as sodium, potassium and aluminum to yield corresponding alkoxides and liberate hydrogen.
In the light of the above statements, choose the correct answer from the options given below:
Which of the following configurations represents atoms of the elements having the highest second ionization energy

The energies of activation for forward and reverse reactions for $A_2 + B_2 \rightleftharpoons 2AB$ are $180\, kJ\, mol^{-1}$ and $200 \,kJ\, mol^{-1}$ respectively. The presence of a catalyst lowers the activation energy of both (forward and reverse) reactions by $100\, kJ\,mol^{-1}.$ The enthalpy change of the reaction $(A_2 + B_2 \rightarrow 2AB)$ in the presence of a catalyst will be ( in $kJ\, mol^{-1}$)
