Geometrical Isomerism: When Structure Changes Everything
Geometrical isomerism (cis-trans isomerism) occurs in molecules with restricted rotation around a bond, typically a double bond or within a ring system. In such isomers, substituents are arranged differently in space. In the cis isomer,...

TED-Ed: How do your hormones work? - Emma Bryce
Over our lifetimes, our bodies undergo a series of extraordinary metamorphoses: we grow, experience puberty, and many of us reproduce. Behind the scenes, the endocrine system works constantly to orchestrate these changes. Emma Bryce...

Why Alkanes Can’t Do Geometrical Isomerism: Find Out!
Alkanes do not exhibit geometrical isomerism because they only contain single bonds (sigma bonds), which allow for free rotation. Geometrical isomerism requires restricted rotation, such as in double bonds or cyclic structures, which is...
