Why can鈥檛 molecules with the following formulas exist

a) CH5 (b)C2H6N(c)C3H5Br

Short Answer

Expert verified

Answer

The formula C2H6Ncan鈥檛 exist.

Step by step solution

01

Stability of molecule

A structure formed by the guidelines of octet and valence electrons is considered stable. In contrast, a system with atoms without an entire outer shell of electrons is unstable.

02

Given molecule can’t exist

The formulaC2H6N requires that carbon exceeds four bonds, or be short of two outer shell electrons or nitrogen should remain except for three bonds.

03

Evidence for non-existence

The structures are represented as follows.

C-N bond formation
