The compound that will undergo $\text{S}_\text{N}1$ reaction with the fastest rate is:
Consider the following reaction in a sealed vessel at equilibrium: $2\text{NO}(g) \rightleftharpoons \text{N}_2(g) + \text{O}_2(g)$ [Given: $[\text{N}_2]=3.0 \times 10^{-3}\text{ M}$, $[\text{O}_2]=4.2 \times 10^{-3}\text{ M}$ and $[\text{NO}]=2.8 \times 10^{-3}\text{ M}$] If $0.1\text{ mol L}^{-1}$ of $\text{NO}(g)$ is taken in a closed vessel, what will be the degree of dissociation ($\alpha$) of $\text{NO}(g)$ at equilibrium?

2,3-dimethyl-2-butene can be prepared by heating which of the following compounds with a strong acid?
In the following reaction, $$ CH_3-C \equiv CH \xrightarrow[873 K]{\text{Red hot iron tube}} A $$ The number of sigma ($\sigma$) bonds present in the product $A$ is:
The compound obtained by addition of water to an alkyne having more than two carbons, in the presence of $\text{HgSO}_4$ and dilute $\text{H}_2\text{SO}_4$ at $333\text{ K}$, is:
Given compounds are as follows: (I) (II) (III). The enthalpy of hydrogenation of these compounds will be in the order as-
Given below are two statements: Statement I: The boiling point of three isomeric pentanes follows the order, n-Pentane > Isopentane > Neopentane. Statement II: When branching increases, the molecule attains the shape of a sphere. This results in smaller surface area for contact, due to which the intermolecular forces between the spherical molecules are weak, thereby lowering the boiling point.
The alkane that gives only one monochloro product on chlorination with $Cl_2$ in presence of diffused sunlight is:
Hydrocarbon (A) reacts with bromine by substitution to form an alkyl bromide which by Wurtz reaction is converted to a gaseous hydrocarbon containing less than four carbon atoms. The formula of (A) is:
An alkene on ozonolysis gives methanal as one of the products. Its structure is:
