This is a precipitation reaction.
2-butanol reacts with Lucas reagent (conc. HCl and ZnCl2) to form a turbidity or a cloudy appearance immediately, indicating a positive result for the presence of a primary or secondary alcohol. This reaction occurs due to the formation of an alkyl chloride, which is insoluble in water and causes the turbidity.
This reaction is called polymerization.
A chemical reaction called a synthesis or combination reaction causes elements and compounds to join together to form new compounds. In this type of reaction, two or more reactants combine to form a single product.
stimulus
Alcohol causes the loss of brain cells and it poisons your liver. Some people develop a physiological dependence on alcohol. Attempting to withdraw on your own from alcohol when a physiological dependence is present can be life threatening. This kind of withdrawal should only be done in the context of an approved medical detox.
drinking alcohol does slow down your reaction but it does not avoid accidents it only causes them.

A stimulus is something that triggers a response in a living organism. This response could be physiological, behavioral, or emotional in nature.
Adrenaline (Epinephrine for the Americans!)
Substances like alcohol, opioids, benzodiazepines, and stimulants can lead to physiological and psychological dependence when used repeatedly. These substances can alter brain chemistry, leading to cravings, withdrawal symptoms, and difficulties in controlling their use.
The main causes of drunk driving accidents are alcohol impairment, poor decision-making, and reduced coordination and reaction time.
Fear is a physiological response that causes butterflies in the stomach. Fear can also cause sweating, loss of voice, and extreme shyness.
The physiological condition that causes you to feel hunger is the release of a hormone called ghrelin in your body, which signals to your brain that you need to eat.
The alcohol used causes the precipitate to form due to a reaction allowing the hydrogen bonds between the nucleotides to form, which causes the DNA to become efficient packed and twisted together.
Alcohol causes over-activity of tear glands in some people. This causes watering of the eyes, and smearing of mascara. It is also not uncommon to have a reaction to some ingredient in a mixed drink. Finally, as alcohol breaks down inhibitions, it is not unusual to have an impulse to cry, causing more tearing.
No contest, alcohol
