Question

draw the electron dot structure of ethyne and also draw its structural formula.

Answer 1

hope this may help you

Answer 2

Electron dot structure and formula of ethyne is as follow:--

●Ethyne belongs alkynes which are unsaturated hydrocarbon and carbon are bonded to each other by triple bond.

●General formula is CnH2n-2 and simplest member is ethyne with two carbon also known as acetylene.

●Carbon are sp hybridised and the bond angle is 180°.The two unhybridised p orbital lie perpendicular to axis of hybridised orbitals.

●The triple bond has one sigma bond and two pie bond.Due to two pie bond they have restricted rotation.

●Bond length between carbon and carbon is 120pm and between carbon and hydrogen is 106pm.
