(Note: For GI, each sp 2 carbon should have two different group)

Q. In which compound cis-trans nomenclature cannot be used:

$C H_{3} - C H = C H - COO H$

$C_{6} H_{5} - C H = C H - C_{6} H_{5}$

$C_{6} H_{5} - C H = C HD$

If across double, each $s p^{2}$ carbon should have at least one identical group, then show cis-trans isomerism.
(Note: For $G I$ , each $s p^{2}$ carbon should have two different group)

Q. In which compound cis-trans nomenclature cannot be used:

CH3​−CH=CH−COOH

C6​H5​−CH=CH−C6​H5​

C6​H5​−CH=CHD

If across double, each sp2 carbon should have at least one identical group, then show cis-trans isomerism. (Note: For GI, each sp2 carbon should have two different group)

$C H_{3} - C H = C H - COO H$

$C_{6} H_{5} - C H = C H - C_{6} H_{5}$

$C_{6} H_{5} - C H = C HD$
