NEET-11-conformers

Conformers are a typical area of isomers. It is to know , how they form?

Conformers refer to different spatial arrangements (shapes) of the same molecule, arising from rotation around single bonds, like the staggered and eclipsed forms of ethane, interconverting easily at room temperature; in biology, conformers are organisms (like most animals and plants) that match their internal environment (e.g., temperature) to the external surroundings, lacking strong internal regulation (homeostasis). The term also appears in AI, as in the Conformer model for speech recognition, combining Transformers and CNNs. 

In a Newmann projection, the three lines in the shape of a Y represent the three bonds of the first carbon that are sighting down; where the three lines connect is where the front carbon is. A circle represents the back carbon; the three lines coming out of the circle represents the three bonds that come off of that carbon. Note that the fourth bond for each of these carbons is the carbon-carbon bond that is looking down. A Newmann projection can help to analyze the rotation around a particular carbon-carbon bond.
