Write bond line formula for 2-methylbutanal

Answer

B

Explanation

`I_(2(s))rarrI_(2)(g)`
`DeltaH_(2)=DeltaH_(1)+DeltaC_(P)(T_(2)-T_(1))`
`DeltaC_(P)=C_(P)(I_(2,g))-C_(P)(I_(2,s))=-6.2` cal/mole
`DeltaH_(2)=6096 - 6.2 (50)=5786` cal/mole
`DeltaH=DeltaU+1xx2xx523`
`5786 =DeltaU+1xx2xx523`
`DeltaU=5786 - 1046 = 4740` cal
