Does resorcinol give iodoform test?

No. The reason being that carboxylic acid and its derivatives do not give iodoform test. This is because due to resonance there is no free existence of C=O.

Which will give iodoform test positive?

Hint: Methyl ketones give positive Iodoform test. Explanation: Iodoform test is used to detect alcohols and ketones having CH3CO− (methyl ketone) group. In the Iodoform test, a compound having methyl ketone reacts with Iodine in presence of base forms haloform which is a yellow precipitate.

Which compound will show iodoform test?

Iodoform test is used to check the presence of carbonyl compounds with the structure R-CO-CH3 or alcohols with the structure R-CH(OH)-CH3 in a given unknown substance. The reaction of iodine, a base and a methyl ketone gives a yellow precipitate along with an “antiseptic” smell.

Do amines give iodoform test?

In Iodoform test the mechanism involves the addition of amine to iodo carbene, no alpha hydrogen should be present to the amine group, and otherwise amine formation takes place. But ethylamine & diethylamine both have alpha hydrogen. Thus, both will give negative iodoform tests. Hence, the correct answer is option (C).

Which compound does not give iodoform test?

Hence, Propan-1-ol is the compound that does NOT give iodoform test.

Which of the following gives negative iodoform test?

Hence, negative iodoform test is given by Benzyl alcohol.

Which of the following compound will not give positive iodoform test?

only methanol does not give positive iodoform test.

How will you distinguish between methylamine and dimethylamine?

Solution 1 Methylamine and dimethylamine can be distinguished by the carbylamine test. Carbylamine test: Aliphatic and aromatic primary amines on heating with chloroform and ethanolic potassium hydroxide form foul-smelling isocyanides or carbylamines.

How will you distinguish between ethylamine diethylamine and triethylamine?

Answer. Using the HNO2, you can distinguish between ethylamine, diethylamine, and triethylamine. When you the nitrous acid with the ethylamine, evolution of the nitrogen gas during the reaction make the ethylamine give a brisk effervescence.

Which does not give iodoform test?

Compounds containing either CH3C∣HOH or CH3C∣=O group, on reaction with NaOH and I2 form yellow coloured iodoform. This is called the iodoform test. Hence, C6H6OH does not give the iodoform test.
