Tips for the Diploma

Question 1

Which types of molecules have ionic bonds and which have covalent?

a. organic
b. inorganic

Answer 1

organic compounds (i.e. compounds without metals) have covalent bonds (electrons are shared) 
inorganic compounds (i.e. compounds with metals) have ionic compounds (electrons are transferred)

Question 2

Which produces more energy?

a. cellular respiration in cells (burning glucose in your body)
b. burning glucose over a flame

Answer 2

a. cellular respiration produces more energy because it occurs in a closed system and the water stays liquid (with the flame, water is turned to gas, which takes energy)

Question 3

What is an “alkyl” functional group?

Answer 3

alkyl = only made of carbon and hydrogen

ex. CH3

Question 4

If the K value is larger, does it means the products or reactants are favoured?

Answer 4

products

larger K means higher concentration of products

Question 5

What is the formula (ex. CnH2n+2) for alkane, alkene, alkyne?

Answer 5

alkane: CnH2n+2
alkene: CnH2n
alkyne: CnHn
