Free rotation is possible with respect to a C-C bond in the case of alkanes. c) An alkene on ozonolysis followed by reduction of the ozonide formed with zinc and water gave a mixture of ethanal and methanal. ii) Illustrate the above mentioned the above mentioned reaction using the chemical equation.

Free rotation is possible with respect to a C-C bond in the case of alkanes. b) Draw Newman's projections of the two conformers of ethane. Which among these is more stable? Justify.

Free rotation is possible with respect to a C-C bond in the case of alkanes. a) The repulsive interaction between the adjacent bonds in a conformation is called…...

Read the following statements and find out the incorrect statements. a. Ovules generally differentiate a single megaspore mother cell (MMC) in the chalazal region of the nucellus. b. The MMC undergoes reduction division and produces four megaspores. c. In a majority of angiosperms, one of the megaspore is degenerated while the other three remains functional. d. The nucleus of the functional megaspore divides mitotically three times and form 2-nucleate, 4-nucleate and later 8-nucleate stages of the embryo sac. e. These mitotic division are strictly free nuclear, that is, nuclear division are immediately followed by cell wall formation.

An alkene 'A' contains 3 C-C, 8 C-H sigma bonds and 1 C-C pi bond. 'A' on ozonolysis gives two moles of an aldehyde of molar mass 44u. Write the IUPAC name of 'A'

A spacial arrangements of atoms which can be converted into one another by rotation arround a C-C single bond are called conformations. i) Represent Sawhorse and Newman projection formulae of staggered and eclipsed conformation of ethane.

A ketone (A) which undergoes halaform reaction gives compound (B) an reduction. (B) on heating with H_2 SO_4 gives (C) which forms monoozonide (D). (D) on hydrolysis in presence of zinc -dust gives only accetaldehyde. Identify (A) (B) and (C). Write the reactions invoived.
