प्रश्न

A saturated hydrocarbon has fifty hydrogen atom in its molecule. The number of carbon atoms in its molecule will be
(a) twenty five
(b) twenty four
(c) twenty six
(d) twenty seven

उत्तर

twenty four
Alkanes are saturated hydrocarbons that have the general formula CnH2n+2. According to the question, the number of hydrogen atoms is 50, i.e., 2n+2=50.
∴ n = 48/2 = 24

Identify the incorrect statement and correct them.

  1. Like covalent compounds, coordinate compounds also contain charged particles (ions). So they are good conductors of electricity. 
  2. Ionic bond is a weak bond when compared to Hydrogen bond.
  3. Ionic or electrovalent bonds are formed by mutual sharing of electrons between atoms. 
  4. Loss of electrons is called Oxidation and gain of electron is called Reduction.
  5. The electrons which are not involved in bonding are called valence electrons.

Statement (A): Covalent compounds are bad conductors of electricity.
Reason (B): Covalent compounds contain charged particles (ions)
