The quantity of electricity produced in the oxidation of 67.2 L of \(H 2\) at STP is:

Read the passage carefully and answer the Questions
Carbonyl compounds such as aldehydes, ketones, and carboxylic acids play an important role in the biochemical process of plants and animal kingdom. Many aldehydes and ketones find applications in dye, perfumery and other industries.
The carbonyl carbon atom is \(s p^2\)-hybridized forming three sigma and one pi-bond with oxygen.
C-O bonds are polar bond due to high electronegativity of oxygen than carbon.
Hence the carbonyl carbon behaves as an electrophilic center and oxygen as a nucleophilic centre.
Primary and secondary alcohols yield aldehydes and ketones respectively upon oxidation with variety of oxidizing agents.
The boiling points of aldehydes and ketones differ from hydrocarbons and ethers.
Aldehydes and ketones undergo nucleophilic addition reaction due to presence of electrophilic carbonyl carbon.
Nucleophile and a proton add across the carbon oxygen double bond.
Identify the product Y in the following reaction.
\(CH_3-CH=CH-CH_2 OH \xrightarrow{\text { Pyrididium Chlorochromate }} Y\)

Which of the following reagents can bring about the given conversion?
3-Nitrobromobenzene to 3-Nitrobenzoic acid

Sometimes the change in allele frequency is so different in the new sample of the population in which they become a different species. This phenomenon is known as

A card from a pack of 52 cards is lost. From the remaining cards of the pack, two cards are drawn and are found to be heart. Then the probability of the missing card to be a heart is:

When 1 mol of CrCl\(_3\) \(\cdot\) 6H\(_2\)\(O\) is treated with excess AgNO\(_3\), 3 mol of AgCl are obtained.
The conductivity of the solution will correspond to:
