Mixed Chemistry

This option is correct because these are dependent on the reactivity rules. Hence, more reactive metal displaces the less reactive metal, according to reactivity series silver cannot displace copper therefore it does not react with copper.

This option is correct because the phenol and formaldehyde undergoes reaction and futher linking to produce backlite (thermosetting polmers).

This option is correct because vitamin K is obtained from green leaves of  cauliflower, cabbage, etc. Its main function is helping in blood coagulation and its deficiency delays the coagulation period. Vitamin K is, hence also known as antihaemorrahagic.

This option is correct, as the Clemmensen's reduction involves the reduction of aldehyde and ketone in presence of  zinc amalgam, and HCl. It produces alkanes. Acetone is reduced in to propane.

This option is correct, as arsenic chloride is added in acetylene in presence of AlCl₃, Cu₂Cl₂ to form 2-chlorovinyldichloroarsine. This is Lewisite. it is very powerful poisonous gas.

This option is correct because the Hofmann and Hinsberg's reagent is used in the separation of amine from the mixture of primary, secondary and tertiary amine.

This option is correct because hot and concentrated nitric acid reacts with Cu, and produces N₂ gas.

This option is correct because hexamethylene diamine and adipic acid condenses to remove water and makes a large unit of compound called nylon-6, 6.

This option is correct because the Alkyl iodide is prepared by the treatment of primary alkyl halides with alkali metal halides leads to the replacement of halogen to formed the alkyl iodide.

This option is correct because bezene is treated with acetyl chloride, in presence of anhydrous aluminium chloride to form acetophenone.

This option is correct because the tryosine can represent the aromatic properties. It is a alpha-amino beta(p-hydroxyphenyl) propionoic acid. It has aromatic nucleus. It is aromatic amino acid.

This option is correct because phosphorous chloride reacts with water and produces orthophosphoric acid. It is called phosphorous acid.

This option is correct because primary amine on treatment with chloroform and KOH produces ethyl carbylamine.

This option is wrong because white phosphorus shines in darkness due to its slow combustion in the air. It is produced by phosphorus pentaoxide.

This option is correct because the acetaldehyde gives a pink colour with Schiff's reagent while acetone does not respond to this test.
