Predict the products for each of the following reation a. H3C-CH2-CH3 + heat + Cl2 -->

b. H3C-CH2-CH=CH-CH3 + heat + Br2

answerleaving cheese out to get moldy;

answer : third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

explanation :

let us write down the given equations

equation 1 :

equation 2 :

equation 3 :

let us use hess's law to find out which 2 equations can be added to get the third equation.

let us reverse equation 2 and multiply it by 2. the new equation that we get is,

equation 4 :

let us add equation 1 & 4

the above equation is similar to equation 3 but has different value for dhrxn.

therefore third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

the answer is 0.42 is that is an option. this question provides no info
