Concept explainers
Interpretation:
From the options given, the answer that best suits the following question has to be identified.
“Why there are no pi bonds in ethane?”
- (a) The remaining unhybridized p-orbitals do not contain any electrons.
- (b) There are no unhybridized p-orbitals on either of the C-atom.
- (c) The remaining unhybridized p-orbitals are not parallel to each other.
Concept Introduction:
Hybridization is a hypothetical concept. It refers to overlapping of atomic orbitals and the resultant orbitals formed are known as hybrid orbitals. An orbital that doesn’t involve in hybridization is termed as unhybridized orbital. After hybridization, the orbitals cannot be distinguished individually. The orientation of the orbitals while overlapping impacts the nature of the bond forms.
A bond between two atoms is known as sigma bond if the atomic orbitals of the atoms overlap end to end – it is also called head on overlapping. A bond is said to pi bond if it is formed by sideways overlapping of atomic orbitals of the atoms.

- One liter of N2(g) at 2.1 bar and two liters of Ar(g) at 3.4 bar are mixed in a 4.0 liter flask to form an ideal gas mixture. Calculate the value of the final pressure of the mixture if the initial and final temperature of the gases are the same. Repeat this calculation if the initial temperature of the N2(g) and Ar(g) are 304 K and 402 K, respectively, and the final temperature of the mixture is 377 K.arrow_forward10 5 4.
