Which of the following statements is INCORRECT in case of Hofmann bromamide degradationn?

Correct Answer - C Amorphous solids have no orderly arrangement of particles i.e., they are isotropic

Correct Answer - D HF is more stable than HCl. The reson is that in the formation of HF, more energy is produced. It means, HF has less energy than HCl...

Correct Answer - B Hofmann bromamide reaction is `R-oversetoversetO(||)C-NH_2+Br_2 + 4KOH oversetDeltato underset"Primary amine"(R NH_2) + K_2CO_3 + 2KBr + 2H_2O` This reaction is given by primary amide only. Option (b)...

Correct Answer - C Mustard oil reaction is `RNH_2 + S = C =S overset(Delta)to R NH-undersetundersetS(||)C-SH overset(HgCl_2)to underset"Alkyl isothiocyanate"(R-N=C=S)+HgS + 2HCl`

Correct Answer - D Sucrose obtained from cane sugar. On hydrolysis of sucrose it gives equimolar mixture of D (+)-glucose and D (-)-fructose. Sucrose is a non-reducing sugar. Sucrose `underset"or invertase"overset(H^+)to...

Correct Answer - 1 `DeltaG^(@)` is not always zero at equilibrium

Correct Answer - C Brass is a solution of solid in solid (Cu+Zn).

Correct Answer - D These are chemical twins Zr belongs to 5th period and 4th group. Hf belongs to 6th period and 4th group.

Correct Answer - C `R hArr P` `R_f =K_f [R]`….(1) `R_b = K_b [P]`….(2) Equation (2) `divide` Equation (1) `R_b/R_f=K_b/K_fxx "[P]"/"[R]"` or `R_b/R_f=K_b/K_f Q` or `Q=R_b/R_f xx K_f /K_b`
