Answer 2

Answer: 14 g H2

Explanation:

Bond pair in C2H6 = total atoms -1 = 8-1 = 7  

Bond pair in C2H2 = 4-1 =3

Bond pair in H2 = 2-1 =1

Bond pair in CO2 = 3-1 =2

Moles of C2H6 = 30 g = 1 mole

Now,total bond pairs in ​C2H6 = 6.022 x 1023 x2  

Moles of C2H6 =24g/26 g = 0.92 mole

Now,total bond pairs in C2H2 = 6.022 x 1023 x 0.92 x 3 =​ 6.022 x 1023 x 2.76

Moles of H2 = 14/2 = 7  

Now,total bond pairs in H2 = 6.022 x 1023 x 7 x 1 =​ 6.022 x 1023 x 7

Moles of CO2 =88/44 = 2

Now,total bond pairs in CO2 = 6.022 x 1023 x2 x 2 =​ 6.022 x 1023 x 4

Hence the largest bond pairs will be found in H2
