An alkene and an alkyne is to be defined. Their general formula and the bond angles between them are to be stated. Bonding in alkenes and alkynes using C 2 H 4 and C 2 H 2 is to be described and the reason for the restricted rotation between them is to be stated. To decide weather C n H 2n is general formula of cyclic alkene and if not, then their general formula is to be stated. Concept introduction: Unsaturated hydrocarbons are characterized by the presence of double bonds or triple bonds linking carbon atoms in a chemical compound. However, in saturated hydrocarbons, the carbon atoms are linked by the single bond.

Answer 1

Question

Definition Definition Molecules that have multiple bonds between their carbon atoms. Alkenes are hydrocarbons with a double bond between two adjacent carbon atoms (R 2 C=CR 2 ), whereas alkynes are hydrocarbons with a triple bond between two adjacent carbon atoms R-C=C-R . These two groups are known as unsaturated hydrocarbons. They have fewer hydrogen atoms when compared with alkanes with same number of carbon atoms. The general molecular formula for an unsaturated hydrocarbon can be represented as C n H 2n +2 .

When 15.00 mL of 3.00 M NaOH was mixed in a calorimeter with 12.80 mL of 3.00 M HCl, both initially at room temperature (22.00 C), the temperature increased to 29.30 C. The resultant salt solution had a mass of 27.80 g and a specific heat capacity of 3.74 J/Kg. What is heat capacity of the calorimeter (in J/C)? Note: The molar enthalpy of neutralization per mole of HCl is -55.84 kJ/mol.
