To draw the molecules N2H2, N2H4, C2H2, C2H4, and H3COH3, we need to understand the basic structure and bonding of each molecule. Here’s a step-by-step guide:
N2H2 (Hydrazine)
This molecule consists of two nitrogen atoms bonded to each other, with each nitrogen also bonded to one hydrogen atom. Place two nitrogen atoms side by side, connect them with a triple bond, and then add a hydrogen atom to each nitrogen. Remember to include lone pairs: each nitrogen atom should have one lone pair.
N2H4 (Hydrazine)
N2H4 is similar to N2H2 but has two additional hydrogen atoms. Start with the two nitrogen atoms connected by a single bond. Add two hydrogen atoms to each nitrogen atom and account for the lone pairs on each nitrogen (one pair each).
C2H2 (Acetylene)
This molecule has two carbon atoms connected by a triple bond. Each carbon should have one hydrogen atom bonded to it. Visualize it as C≡C with a hydrogen atom attached to each carbon.
C2H4 (Ethylene)
C2H4 consists of two carbon atoms connected by a double bond, with two hydrogen atoms bonded to each carbon. Draw it as C=C with two hydrogens on each carbon. There are no lone pairs in this molecule.
H3COH3 (Dimethyl Ether)
This molecule consists of a carbon atom bonded to three hydrogen atoms and an oxygen atom. Draw the carbon as a central atom connected to another carbon, which is also connected to three hydrogens, and the oxygen is connected between the two carbon atoms. There are no lone pairs on the outer carbons or oxygen.
Connecting these atoms visually can help you understand their spatial arrangements. Remember, using Lewis structures is key to properly representing each molecule’s bonds and lone pairs.
