Following experiments examine the effect on the rate of (a) the halogen is changed and (b) primary, secondary ry halogenoalkanes and a halogenoarene are used.
At the end of cal, the two immiscible layers in the combined waste can to cite this of reaction of the halogenoalkanes essay.
Plan for rate of reaction for halogenoalkanes aim === aim of the experiment is to find out and compare the rate of displacement of the halide ion and how is varies with respect to the carbon halogen bond.
General equation: general formula: r-x +: nu- ® r-nu + x- cnh2n+1x (where x is the halogen) background information halogenoalkanes ====================================== in the reaction of halogenoalkanes bond polarity show us that c-f would be the most reactive then c-cl, c-br and c-i would be the lest reactive....
In primary halogenoalkanes the halogen atom is covalently bonded to a carbon atom which is bonded to one other carbon, to two other carbons in secondary and three others in tertiary.
Rates of reaction of the halogenoalkanes scientific knowledge and understanding: halogenoalkanes are classified as either primary, secondary or tertiary.
This is because silver nitrate is a when dissolved in water will form ag+ and no3- ions, neither react with the halogenoalkanes.
These are marked by other units are assessed by written coursework, which is initially assessed by the school/college and then checked by aqa.
75% of the course is portfolio based, this makes up the coursework course it taught over 5 lessons a week during year 10 and 11.
Please try again hed on dec 12, 2016use iupac rules to name alkanes, alkenes, alkynes and halogenoalkanesdistinguish between saturated and unsaturated rd youtube autoplay is enabled, a suggested video will automatically play hydrocarbons 2/2 "aldehydes - ketones - ethers - carboxylic acids - esters".
During practical based activities students will be paired up often allowing a less confident student to be supported by a more confident the student work is portfolio based for 2 units it is vital that they are producing high quality work independently, so after group discussions and sharing of ideas pupils will produce their own reports, developing the ideas in their own weighting of each module towards overall grade:All units have an equal weighting in the as and s of any coursework:Unit 1: 4 work place reports, 1 health and safety study, 1 impacts on society report, 2 lab 2: 1 energy policy report, 1 energy resource comparison report, 3 lab reports, (qualitative, quantitative and chromatography).
Alcohols, halogenoalkanes and f323: practical skills in chemistry as (practical skills) unit is teacher assessed and externally moderated by ocr.
