Halogenoalkanes and hydrolysis (6.3 1)

Question 1

Halogenoalkanes

Answer 1

homologous series of compounds CnH2n+1X.
result of replacing h atom with halogen atom
X usually bromine of chlorine
R=alkyl group
RX

Question 2

Number of halogen atoms

Answer 2

can be more than one
CnH2nX2
CnH2n-1X3

Question 3

Name examples

Answer 3

1,2-dichloropropane
tetrachlormethane
2-fluorobutane

Question 4

if two more diffrent halogen

Answer 4

prefixes appear in alphabetical order

Question 5

classification of halogenoalkanes

Answer 5

primary how many alkyl groups joined to c atom bonded to halogen atom

Question 6

polarity

Answer 6

halogen atom has an electronegativity higher than carbon so C-X bond polar

Question 7

Down group 7

Answer 7

electronegativities of halogens decrease from fluorine to iodine so polarity of C-X bonds decreases

Question 8

carbon atom joined to halogen

Answer 8

always slightly positive or electron deficient .Attracts Nucleophiles-always use lone pair of electrons when attacking (any situation)

Question 9

Hydrolysis reactions

Answer 9

water molecule contains polar bond negative o attracted to positive c
RX +H2O=ROH+HX
Product alcohol and organic substance -colorless liquids no color change can be seen
c-x bond breaks so R and X separates and R group them combines with OH of water.
Hydro=water
Lysis =splitting
