All of the following statements about oxidation of carbonyls are true except .a. Tollens' test involves reduction of Ag⁺. b. oxidation of aldehydes produces carboxylic acids. c. oxidation of ketones produces esters. d. Benedict's test involves reduction of Cu²⁺.

C

Explanation:

Amongst the options in the question, the option that ketones oxidizes to esters is wrong.

Aldehydes and ketones belong to a group of organic compounds called the carbonyls. Both are functional group isomers and are characterized by the bond C=O

When ketones or alkanones are oxidized, there are series of products which are formed. For the ketones, the highest or end point of their oxidation is the carboxylic or alkanoic acid and not the esters.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
