Question
Consider the molecule below and answer questions 2-4 2. What is the hybridization of the (i) C atom attached to the S atom and the (ii) P atom? (1 mark) (a) (i) sp?. (ii) sp (b) (i) sp3. (ii) sp (c) (i) sp3. (ii) sp (d) (i) sp, (ii) sp (e) (1) sp?, (ii) sp () None of the above combinations are correct. ANSWER: 3, How many -bonds are there? (1 mark) (a) Eight (b) Seven (d) Ten (e) Twelve (f) Fourteen (c) Six ANSWER: 4. How many carbons are sp hybridized in this molecule? (1 mark) (a) Seven (b) Six (c) Two (d) Three (e) Nine ANSWER:Explanation / Answer
2)
i) C atom forms 3 sigma and 1 pi bond
pi bond is not considered in hybridisation
So, the C is sp2 hybridised
ii)
P forms 1 sigma, 2 pi and has 1 lone pair
pi bond is not considered in hybridisation
So, the P is sp hybridised
Answer: e
3)
pi bond are all other bonds except single bond
There are 3 in ring
1 with S
1 between 2 Carbon atoms
2 with P
Total 7
Answer: b
4)
all carbons in ring are sp2 (6)
C with S is sp2 (1)
both C that has double bond between them (2)
total 9
Answer: e
