What is the prefix if the number of carbon atoms is $$3$$?

Reaction mechanism describes:

Observe the following pairs of organic compounds :
(I) $$C_4H_9OH$$ and $$C_5H_{11}OH$$
(II) $$C_7H_{15}OH$$ and $$C_5H_{11}OH$$
(III) $$C_6H_{13}OH$$ and $$C_3H_7OH$$
Which of these pair is a homologous series according to increasing order of carbon atom ?

An organic compound $$X$$ give following laboratory tests.
(i) It gives white precipitate with tollen's reagent
(ii) it gives +ve iodoform test
(iii) It gives lucas test within 5 min
$$X$$ can be:

The nodal plane in the $$\pi$$ bond of ethene is located in:

Which statement about a homologous series is incorrect?

Why is functional group important?

Compound '$$A$$' on treatment with copper at $$300^\circ$$C gives '$$B$$' and a gas '$$C$$'. It is possible to get back '$$ A$$' from $$B$$ and $$C$$. In presence of '$$D$$', both $$B$$ and $$A$$ on treatment with certain reagent gives same compound '$$E$$', which on treatment with '$$A$$' gives compound $$F$$ with a fruity smell. Identify the compounds and isomer of 'F'.

Which of the following group is sharp ortho and para directive?
