The alkane that gives only one monochloro product on chlorination with \(\text{Cl}_2\) in presence of diffused sunlight is-

In the following reaction,

\(\mathrm{ CH_{3}C\equiv CH\xrightarrow[Red \ hot \ iron \ tube]{873 K} \ A}\)

The number of ($\sigma$) bonds present in the product (A) is:

2,2–dimethylpropane, C(CH₃)₄, is an isomer of pentane, CH₃(CH₂)₃CH₃. Pentane has a boiling point of 36 °C whilst the boiling point of 2,2–dimethylpropane is 10 °C.

The statement that explains the difference in the boiling points for these two substances is: 

Which of the following would exhibit cis-trans isomerism?

1. ${\mathrm{CH}}_3{\mathrm{CH}}_2\mathrm{CH}={\mathrm{CH}}_2$

2. $\mathrm{ClCH}=\mathrm{CHCl}$

3. $\mathrm{ClCH}={\mathrm{CCl}}_2$

4. ${\mathrm{CH}}_2=\mathrm{CH}-\mathrm{COOH}$

In the following reaction,

the number of ($\sigma$) bonds present in the product (A) is-

The most suitable reagent for the following conversion is-

1.  Hg²⁺/ H⁺, H₂O

2. Na/liquid NH₃

3. H₂, Pd/C, quinoline

4. Zn/HCl

An alkene "A" on reaction with ${\mathrm{O}}_3$ and $\mathrm{Zn}-{\mathrm{H}}_2\mathrm{O}$ gives propanone and ethanal in equimolar ratio. The addition of HCl to alkene "A" gives "B" as the major product. The structure of product "B" is:
