differences in solubilities between the two molecules. Polarity also played a role in the alcohol reactions: water‚ which is polar‚ will be insoluble with 1-octanol (which is nonpolar)‚ insoluble with 1-butanol (also nonpolar)‚ and soluble with methanol (polar). But it’s a little more complicated: the carbon chain of each of these organic compounds will always be nonpolar and therefore hydrophobic‚ but as these are alcohols‚ the -OH group‚ which is polar and therefore hydrophilic‚ comes into play as well

my first alcohol drink I would end up an alcoholic? Not me! It never was my intention to end up like that. But after that first drink‚ something happened‚ inside me. I couldn’t explain it but I liked the feeling. All I knew was‚ my first Bacardi and Coke did something to me that changed the direction of my life‚ for the better‚ I thought‚ but I was wrong. What My First Drink Did For Me Let me explain‚ what my first drink did for me. Sad‚ but true after my first alcoholic drink‚ alcohol became

liquor or the mental illness and compulsive behavior resulting from alcohol dependency. For some people it might just be the occasional night out to relieve some stress‚ but for an alcoholic it’s not only a need‚ it’s a dependency. There are no advantages that can come from abusing alcohol. Alcoholism negativity affects everyone involved – it affects the drinker’s health‚ their family‚ and their way of life. The effects of alcohol vary whether the drinker is male or female‚ adult or adolescent‚ and

of friendships with benefits. They were divided into two sets. The first set pertained to specific demographics and psychosocial predictors of participating in a relationship that was of Friends with Benefits status. This included factors such as alcohol consumption and gender. The second set of hypotheses examined the reactions to FWB relationships. The researchers were interested if the participants thought it was a positive or negative experience afterwards. All-in-all this led the researchers

the alcohol‚ making it either primary (1° )‚ secondary (2° )‚ or tertiary (3° ). If the OH is bonded to only one other carbon‚ it is a primary alcohol (eg. 1-butanol); if bonded to two other carbons‚ it is a secondary alcohol (eg. 2-butanol); if bonded to three other carbons‚ it is a tertiary alcohol (eg. 2-methyl-2-propanol). Due to the placement of the hydroxyl functional group in each of the degrees of alcohol‚ the reactivity of each should be impacted. This means that all three alcohols should

characteristic functional group of alcohols and phenols. On the other hand‚ carbonyl group refers to a divalent chemical unit consisting of a carbon and an oxygen atom connected by a double bond. It is known as the characteristic functional group of aldehydes and ketones instead. In this experiment‚ hydroxyl- or carbonyl- containing samples were given to the group for examination. The samples were analyzed through different tests namely the involvement of the solubility of alcohols in water‚ the Lucas Test

On the other hand‚ some American teenagers also believe if the law allowed the underage drinking‚ we would have several car accidents‚ which happens every day. In the article “Heavy Drinking on College Campuses: No Reason to Change Minimum Legal Drinking Age of 21‚” Drew K. Saylor shows what bad if you drink alcohol underage is‚ and Saylor says

What is Alcohol? Alcohol Alcohol has been around in various cultures for almost 10 000 years. It is widely used in Canada‚ and is closely associated with parties and celebrations. In 2009‚ alcohol was consumed by 77% of Canadians aged 15 and over (Health Canada). It has a huge presence in the College and University environments‚ and most students claim to have drunk alcohol at some point during their time at school. Alcohol is produced by fermenting and sometimes distilling various fruits

stop or even reduce their consumption. However‚ it is usually not ‘them’ but instead their brain that gives in first. What if there was simply a drug that tricked the brain into submission‚ into believing that there was no rewarding effects from alcohol. Relief could be brought to not only the sufferer but to their family‚ friends‚ body‚ and the healthcare system. Well‚ after extensive research‚ Professor Daryl Davies may just have discovered this effortless drug and he has just shared
