$HCCC{O}_{2}H,$ is an organic hydrocarbon.

a$)$ Draw a geometrically accurate structure so that the formal charge of each atom is zero identifying the bond angles $($Draw it BIG!$).$

b$)$ Identify the hybridization about each atom $($not $H)$ forming a bond

c$)$ How many $$ or $$ bonds are there in this molecule

d$)$ The combustion of the hydrocarbon produces carbon dioxide and water in the gaseous state. Use average bond enthalpies to determine enthalpy of reaction
