Draw Lewis structures for the fluoroethene molecule (C2H3F), the acetonitrile molecule (CH3CN), and the acetylene molecule (C2H2) in the window below, and then answer the questions that follow, based on your drawings.

Please check image and explanation

Explanation:

Lewis structure means drawing all the lone pair and bond pair around the atom and also lone pair of electron is represented as pair of dot except in the odd electron system where electron is denoted by only one dot. single bond is denoted by single line and similarly double bond denoted by two parallel line and so on

generally less electronegative atom is taken as central atom or atom having  more covalency.

Explanation:

baking soda, bread soda, bicarbonate of soda, and cooking soda.
