Question

Question 23 For each of the following compounds, use the nitrogen rule to determine whether the molecular weight should be even or odd. he This compound does not have any nitrogen atoms. According to the nitrogen rule, this compound should have an even molecular weight (m/z = 140). O This compound does not have any nitrogen atoms. According to the nitrogen rule, this compound should have an even molecular weight (m/z = 136). O This compound does not have any nitrogen atoms. According to the nitrogen rule, this compound should have an even molecular weight (m/z = 138). This compound does not have any nitrogen atoms. According to the nitrogen rule, this compound should have an even molecular weight (m/z = 142). This compound does not have any nitrogen atoms. According to the nitrogen rule, this compound should have an even molecular weight (m/z = 142). O This compound does not have any nitrogen atoms. According to the nitrogen rule, this compound should have an even molecular weight (m/z = 120). This compound does not have any nitrogen atoms. According to the nitrogen rule, this compound should have an even molecular weight (m/z = 140). This compound does not have any nitrogen atoms. According to the nitrogen rule, this compound should have an even molecular weight (m/z = 122).

Answer 1

111 - Nitrogen fule state that molecular massa molecular weight If Molecular mass of the given organic compound is Odd then it contains odd no of Nitrogen sent then it contain Even No of Nitrogen OR no Nitrogen in the molecular formula of molecular son 1,1,1,, E OR ) Even.
