(A): Phenol is insoluble in $NaHCO _3$ solution but acetic acid is soluble.
Reason (R): Phenols are weakly acidic and hence they dissolve only in strong base and insoluble in weak base like $NaHCO _3$. But acetic acid is a stronger acid than phenol and so it is soluble in weak base $NaHCO _3$.

Assertion (A) - Cr and Cu having $[ Ar ] 3 d^5 4 s^1$ and $[ Ar ] 3 d^{10} 4 s^1$ are more stable.
Reason (R) – The extra stability of elements Cr and Cu is due to symmetrical distribution of electrons and exchange energy.

Assertion (A) – In 3d transition elements, the expected decrease in atomic radius is observed from Sc to V, thereafter upto Cu, the atomic radius nearly remains the same.
Reason (R) – As we move from Sc to V, the added 3d electrons only partially shield the increased nuclear charge but upto Cu, the extra electron added to 3d sub-shell repel the 4s electrons and the slight increase in nuclear charge operated in opposite direction and it leads to constancy in atomic radii.

Assertion (A) – In transition metal series, the ionization enthalpy increases.
Reason (R) – This is due to increase in nuclear charge corresponding to the filling of d electrons.

(A): $5 Br _{\text {(aq) }}^{-}+ BrO _{3 \text { (aq) }}^{-}+6 H ^{+} \rightarrow 3 Br _2$ (l) $+3 H _2 O _{(1)}$.
The overall order of the reaction is equal to 4.
Reason (R): The experimental rate law is.
Rate $= K \left[ Br ^{-}\right]\left[ BrO _3^{-}\right]\left[ H ^{+}\right]^2$.
So $1+1+2=4$ order value is 4 .
