Bond Fission
Flashcards do conjunto (12)
- 1What is bond fission?Breaking a covalent bond
- 2What are the two types of bond fission?Heterolytic fission
Homolytic fission - 3What happens during heterolytic fission?The bond breaks unevenly with one of the bonded atoms receiving both electrons from the bonded pair
- 4What are the products of heterolytic fission?A positively charged cation (X⁺)
A negatively charged anion (Y⁻) - 5Give the general equation for heterolytic fissionXY --> X⁺ + Y⁻
- 6What happens during homolytic fission?The bond breaks evenly and each bonding atom receives an electron from the bonded pair
- 7What are the products of homolytic fission?Two electrically uncharged radicals
- 8What is a radical?Particles that have an unpaired electron
- 9Give the general formula for homolytic fissionXY --> X• + Y•
- 10What is a mechanism?A sequence of steps showing the path taken by electrons in a reaction
- 11Complete the sentences: Reactions occur via a series of different _____________. These processes can be shown step by step using a reaction ______________. Reaction mechanisms use _______ _________ (↷) to show the movement of a _______ ___ __________.Reactions occur via a series of different PROCESSES. These processes can be shown step by step using a reaction MECHANISM. Reaction mechanisms use CURLY ARROWS (↷) to show the movement of a PAIR OF ELECTRONS.
- 12Using curly arrows, show how heterolytic fission occurs in a compound XY
