Bond the following sets of molecules to maximize octets either by gaining, giving, or sharing electrons. Show bonds and lone pair electrons $($this is a Lewis Dot structure$).$

$H_{3}CC{H}_3$

$H_{2}CC{H}_2$

$LiC{H}_{2}C{H}_3$

$C{H}_{3}OH$

$BrC{H}_{2}C{H}_{2}CHNH$

NaCl

Explain in a complete sentence why $Li$ is positive and $C$ is negative $($this is formal charge$).$

$LiC{H}_{2}C{H}_3$

Draw the structure and list what the atoms' electrons are doing in the following molecules. $($core electrons, valence electrons, bonding, and lone pairs$).$

i$.$e$.H_{2}CCFH$

each $H$ has $1$ electron, a valence electron

it is in a covalent bond with $C$

each $C$ has $6$ electrons $-2e-$ in the first shell, core e$-$

$4$ e$-$ in the second shell, valence e$-$

These valence e$-$ are covalently bonding with $-H,C,$ and $-F$

$F$ has $9e--2e-$ in the first shell, core e$-$

$7e-$ in the second shell, valence e$-$

$1$ of these valence e$-$ is covalently bonding to $-C$

$6$ of these valence e$-$ are lone pairs

$ClC{H}_{2}OH$

each $H$ has

$Cl$ has

$C$ has

O has
