Results in a decrease in the number of c-z bonds, where z is an element that is more electronegative than carbon (usually o, n, or x). results in a decrease in the number of c-h bonds. conformations are the different arrangement of atoms that are interconverted by rotation about a single bond. bonds are located in the plane of the chair conformation of cyclohexane. steric strain is an increase in energy resulting when atoms are forced too close to one another.

answer: option (a) is the correct answer.

explanation:

the measurement of hydrogen ions in a solution is known as ph.

if ph of a solution is less than 7 then the solution is acidic. if ph of a solution is greater than 7 then the solution is basic.

when the ph of a solution equals 7, then the solution is considered as neutral.

the ph of pure water is 7, therefore, it means that concentration of hydronium ions equals that of hydroxide ions.
