5. Në cilin vit kimia organike merret si shkencë?

Explanation

In 1928, organic chemistry began to be recognized as a science. This was the year when Friedrich Wöhler synthesized urea, which was the first organic compound to be artificially created from inorganic materials. This breakthrough demonstrated that organic compounds could be produced through chemical reactions, challenging the prevailing belief that organic compounds could only be derived from living organisms. This discovery revolutionized the field of chemistry and solidified organic chemistry as a distinct scientific discipline.

6. Formula e përgjithshme e alkaneve është?

Explanation

The general formula for alkanes is R-H. Alkanes are hydrocarbons that consist of only carbon and hydrogen atoms. In the general formula, R represents any alkyl group, which is a group of carbon and hydrogen atoms attached to a larger molecule. The -H represents a hydrogen atom bonded to one of the carbon atoms in the alkyl group. This formula applies to all alkanes, regardless of their specific structure or number of carbon atoms.
