The ratio of sp and sp3 orbitals present in the product formed from the reaction between 1,1,5,5–tetrabromopentane and sodamide?

1,1,5,5–tetrabromopentane will undergo dehydrohalogenation reaction in the presence of and forms penta–1,4–diyne. penta–1,4–diyne is having 4 sp and 1 sp3 carbon.Each sp carbon is having two sp orbitals each sp3 carbon is having four sp3 orbitals. The ratio of sp and sp3 orbitals is 4×21×4=84=2
