#1
Front (Question)

What does VSEPR in VSEPR Theory stand for?

Back (Answer)

Valence Shell Electron Pair Repulsion

#2
Front (Question)

What does VSEPR Theory involve?

Back (Answer)

only outer energy level, electrons pair through bonds or lone pairs, electrons spread out because they repel

#3
Front (Question)

What does repulsion apply to in VSEPR Theory?

Back (Answer)

both bonds and lone pairs

#4
Front (Question)

What are electron domains essentially?

Back (Answer)

negative charge centres

#5
Front (Question)

How many electron domains do double and triple bonds count as?

Back (Answer)

one

#6
Front (Question)

What differs double and triple bonds if both are only one electron domain?

Back (Answer)

they are higher in electron density

#7
Front (Question)

What does the total number of electron domains around the central atom determine?

Back (Answer)

the arrangement of the bonds and the lone pairs in 3D space (shape)

#8
Front (Question)

What is the shape of a molecule based off of?

Back (Answer)

the angle between the bonds

#9
Front (Question)

Why do lone pairs of electrons have a higher charge density than bonding pairs?

Back (Answer)

because the two electrons of the lone pair are not spread between two atoms

#10
Front (Question)

What contributes to a molecule having a distorted shape?

Back (Answer)

having lone pairs of electrons rather than all bonds

#11
Front (Question)

How are shapes of molecules determined?

Back (Answer)

based on how many electron domains the central atom has and how many lone pairs make up those domains

#12
Front (Question)

What is the shape of a molecule with 2 electron domains?

Back (Answer)

linear

#13
Front (Question)

What are the bond angles of the linear shape?

Back (Answer)

180

#14
Front (Question)

What is the shape of a molecule with 3 electron domains, no lone pairs, all bonds?

Back (Answer)

trigonal planar

#15
Front (Question)

What are the bond angles for a trigonal planar shape?

Back (Answer)

120

#16
Front (Question)

What is the shape of a molecule with 3 electron domains, one lone pair, 2 bonds?

Back (Answer)

trigonal planar bent

#17
Front (Question)

what are the bonding angles for a trigonal planar bent shape?

Back (Answer)

<120

#18
Front (Question)

What is a possibility when there are three electron domains?

Back (Answer)

an incomplete octet

#19
Front (Question)

What is the shape of a molecule with 4 bonding domains, no lone pairs, all bonds?

Back (Answer)

tetrahedral

#20
Front (Question)

What are the bond angles for a tetrahedral shape?

Back (Answer)

109.5

#21
Front (Question)

What is the shape of a molecule with 4 electron domains, 1 lone pair, 3 bonds?

Back (Answer)

tetrahedral trigonal pyramidal

#22
Front (Question)

What are the bond angles for a tetrahedral trigonal pyramidal shape?

Back (Answer)

<109.5

#23
Front (Question)

What is the shape of a molecule with 4 electron domains, 2 lone pairs, 2 bonds?

Back (Answer)

tetrahedral bent

#24
Front (Question)

What are the bond angles for a tetrahedral bent shape?

Back (Answer)

«109.5
