Question 3
What is the meaning of Alexander Pope’s epigram: All Nature is but Art, unknown to thee; All Chance, Direction, which thou canst not see; All Discord, Harmony not understood; All partial Evil, universal Good: And, spite of Pride, in erring Reason’s spite, One truth is clear, whatever is, is right. Alexander Pope Alexander Pope was an acclaimed English poet, satirist, and writer who lived during the late seventeenth and early eighteenth centuries. He is best known for his poems “The Rape of the Lock”, “The Dunciad”, and “An Essay on Criticism”.
Answer to question 1
Answer to question 2
1) BrF3 : Since the electronegativity of Br is less than F. Hence the central atom is Br.
Since F has 7 valence electrons.
Hence each F will make 1 bond with Br to complete its octet using 1 out of 7 valence electrons.
Hence 6 valence electrons will be remaining on F i.e 3 lone pairs.
And since Br is making total 3 bonds with 3 F using 3 out of 7 valence electrons.
Hence 4 valence electrons will be remaining on Br i.e 2 lone pairs.
Hence the below structure of BrF3
2) BrF5 : Since the electronegativity of Br is less than F. Hence the central atom is Br.
Since F has 7 valence electrons.
Hence each F will make 1 bond with Br to complete its octet using 1 out of 7 valence electrons.
Hence 6 valence electrons will be remaining on F i.e 3 lone pairs.
And since Br is making total 5 bonds with 5 F using 5 out of 7 valence electrons.
Hence 2 valence electrons will be remaining on Br i.e 1 lone pairs.
Hence the below structure of BrF5
Answer to question 3
Answer and Explanation: The meaning of Alexander Pope’s epigram: “All Nature is but Art, unknown to thee; All Chance, Direction, which thou canst not see; All Discord, Harmony not understood; All partial Evil, universal Good: And, spite of Pride, in erring Reason’s spite, One truth is clear, whatever is, is right.” is that God is the ultimate creator of the world, not man. There are mysteries about the world that will not be able to be understood by man but man must have the belief and faith that all is right and good with the world.
