Which of the following is the electron deficient molecule?
Updated On: Apr 17, 2024
- B2H6
- C2H6
- PH3
- SiH4
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Due to the boron atom's three half-filled orbitals in an excited state, B2H6 is an electron-deficient molecule. B2 H6's structure is shown as follows:
In it, three centre bonds are formed by the involvement of two B-H bond electrons; these bonds are indicated by a dotted line.
Therefore, the correct option is (A): B2H6

P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
