Between the two conformational isomers of cyclohexane, ie, cháir and boat forms, which one is more stable?

Assertion : Tricyclopropyl methyl carbonium ion is more stable than tropylium ion. Reason : Stability of tricycle propyl methyl carbocation is a result of conjugation between the bent orbitals of cyclopropyl ring and the vacant p-orbital of cationic carbon.

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.

In the following question, an Assertion (A) is followed by a corresponding Reason (R). Use the following keys to choose the appropriate answer. Assertion : In the formation of water molecule, both hydrogen and oxygen atoms attain octet of electrons. Reason : Oxygen atom forms two ionic or electrovalent bonds with two hydrogen atoms.

A spacial arrangements of atoms which can be converted into one another by rotation arround a C-C single bond are called conformations. ii) Comapare the stabilities of staggered and eclipsed conformations.

Staggered conformation is more stable than eclipsed from because there is less repulsion between bond pairs of electrons. Draw the cls and trans structures of hex-2-ene.
