Hey there!

[He]2s²2p⁴ is the electron configuration for O (oxygen).

He is the noble has before oxygen. It has 2 electrons.

The s orbital is filled, and there are 4 electrons in the p orbital, so 6 elements over to the right.

This makes a total of 8 electrons.

Hope this helps!

                   In this reaction first of all HBr approaches the triple bond. A Pi Complex (weak inter-molecular interactions) is formed between the two molecules. And the triple bond attacks the partial positive hydrogen atom creating a negative charge on Bromine along with positive charge on itself (Sigma Complex). In second step the negative Bromide attacks the positive carbon of Butyne.</span>
