Answer: Option A. -> Diethyl ether
DIETHYL ETHER IS A COLOURLESS, HIGHLY VOLATILE & FLAMMABLE ORGANIC COMPOUND. IT WAS EARLIER USED FOR ANAESTHESIA BUT AFTER THE DEVELOPMENT OF NON-FLAMMABLE DRUGS, ITS USES AS ANAESTHETIC HAS BEEN REDUCED.

Answer: Option D. -> None of the above
COMPARISON BETWEEN INTER ATOMIC AND INTERMOLECULAR FORCES: (I) BOTH INTER ATOMIC AND INTERMOLECULAR FORCES ARE ELECTRICAL IN ORIGIN. (II) BOTH INTER ATOMIC AND INTERMOLECULAR FORCES ARE ACTIVE OVER SHORT DISTANCES. (III) GENERAL SHAPE OF FORCE-DISTANCE GRAPH FOR BOTH THE FORCES IS SIMILAR. (IV) BOTH THE FORCES ARE ATTRACTIVE UP TO CERTAIN DISTANCE BETWEEN ATOMS/MOLECULES AND BECOME REPULSIVE WHEN THE DISTANCE BETWEEN THEM BECOMES LESS THAN THAT VALUE.

Answer: Option D. -> None
ORGANIC COMPOUNDS NOT ONLY HAVE CARBON BONDS BUT ALSO CONTAIN HYDROCARBONS OR CARBON BONDED TO HYDROGEN. A FEW TYPES OF CARBON-CONTAINING COMPOUNDS, SUCH AS CARBIDES, CARBONATES, SIMPLE OXIDES OF CARBON (SUCH AS CO AND CO2), AND CYANIDES ARE CONSIDERED INORGANIC. WATER DOES NOT CONTAIN ANY CARBON ATOM IN ITS MOLECULE, H2O. SO WATER IS ONLY AN INORGANIC COMPOUND.
