Given below are two statements :
Given: Molar masses of C, H, O, Cl are 12, 1, 16 and 35.5 g mol−1 respectively.
Statement I: In 30%(w/w) solution of methanol in CCl4 (at T K), the mole fraction of CCl4 is equal to 0.33.
Statement II: Mixture of methanol and CCl4 shows positive deviation from Raoult’s law.
In the light of the above statements, choose the correct answer from the option given below :
Which statements are True?
A. In Hoffmann bromamide degradation, 4 moles of NaOH and 2 moles of Br2 are consumed per mole of an amide.
B. Hoffmann bromamide reaction is not given by alkyl amides.
C. Primary amines can be synthesized by Hoffmann bromamide degradation.
D. Secondary amide on reaction with Br2 and NaOH will give secondary amine.
E. The by-products of Hoffmann degradation are Na2CO3, NaBr and H2O.
Choose the correct answer from the options given below:
The incorrect statement from the following with respect to carbohydrates is :
An organic compound (P) on treatment with aqueous ammonia under hot condition forms compound (Q) which on heating with \( \mathrm{Br_2} \) and KOH forms compound (R) having molecular formula \( \mathrm{C_6H_7N} \). Name P, Q and R respectively are :
An organic compound P of molecular formula C6H12O3 gives positive iodoform test but negative Tollens’ test. When P is treated with dilute acid, it produces Q. Q gives positive Tollens’ test and also iodoform test. Identify compound P.
MnO2−4 in acidic medium disproportionates to :
