Question 1

which group is halogen?

Answer 1

17th group
F Cl Br I At Ts

Question 2

how are halogens formed? common name?

Answer 2

halogens are formed when one or more hydrogen carbons in an aliphatic hydrocarbons are replaced by a halogen
alkyl halide

Question 3

how are haloarenes formed? common name

Answer 3

haloarenes are formed by replacing one or more hydrogens from a aromatic ring by a halogen
aryl halide

Question 4

monohaloalkane
(classification)

Answer 4

if a compound contains only one halogen it is called mono halo alkane
(3 tri halo alkane
2 di halo alkane)

Question 5

primary alkylhalide?
(classification)

Answer 5

in primary alkyl halide carbon containing halogen is directly attached to 1 other carbon.
in secondary 2 other carbon
in tertiary 3 other carbon

Question 6

what is allylic carbon and allylic halide?*
(classification)

Answer 6

allylic carbon is the carbon which is directly attached to a double bonded carbon and allylic halide is when a halogen is attached to a allylic carbon

Question 7

benzylic carbon?

Answer 7

sp3 hybridized carbon directly attached to a benzene ring is called benzylic carbon

Question 8

vinylic halide? vinylic carbon?

Answer 8

double bonded carbons are called vinylic carbons and halogens directly attached to vinylic carbons are called vinylic halides

Question 9

aryl halides? aryl carbons?

Answer 9

all the carbons forming a ring in an aromatic compound is sp2 hybridized and called aryl carbons
when halogen is directly attached to such carbons compound is called aryl halide
