Answer:
The Arctic Circle is an imaginary line. It marks the northernmost latitude at which the sun does not rise at least one day a year, and does not set at least one day a year. This makes for long days in summer and long nights during winter.
Explanation:
An Arctic Circle can be defined as an imaginary line of latitude that is drawn parallel to the equator around the Earth, at approximately 66°30′ North.
Basically, the Arctic Circle is described by scientists as the most northerly of the five major circles of latitude and one of the two (2) polar circle of the Earth.
The zone (region) to the South of the Arctic Circle is generally referred to as the Northern Temperate Zone while the zone (region) to the North of the Arctic Circle is called the Arctic.
Furthermore, the Arctic Circle represents or depicts the northernmost latitude at which the centre of the noon is only visible in the winter solstice in December i.e the sun does not rise at least one day a year, and does not set at least one day a year. The above describes the polar night (24 hour sunless night) of the December winter solstice.
In conclusion, the Arctic Circle causes long days in summer and long nights during winter.
Benzene behaves differently from a hydrocarbon which simply contains three c c bonds in that the latter would be expected to react much more readily with H2, Cl2, Br2, HCl
The chemical compound benzene has the molecular formula C6H6 and is an organic chemical. Six carbon atoms are connected in a planar ring to form the benzene molecule, and one hydrogen atom is attached to each one. Benzene is categorised as a hydrocarbon because it solely has carbon and hydrogen atoms.
One of the fundamental petrochemicals, benzoene is a component of crude oil that occurs naturally. Benzene is categorised as an aromatic hydrocarbon because of the cyclic continuous pi bonds that exist between the carbon atoms. PhH is a common abbreviation.
