How many resonance structures does the nitrate ion NO2 -1 have?
3 structures
Show how 1 4 diphenyl 1 3 butadiene might be synthesized from benzaldehyde and an appropriate halogenated compound?
Im not sure how to do this but I am trying to understand this process as well.
What type of hybridisation in benzene?
sp^2 Due to 3 pi bonds, In reality a single pi 'cloud' of 6 delocalised electrons exists around the ring (refer to resonance structure).
What is the Lewis structure for HNNN?
It is a resonance structure with 3 possible Lewis Structures. h-n-n-n n-h-n-n (n-n-h-n is the same thing) n-n-n-h N - 5 Valence Electrons H - 1 (will be used to bond)
How many covalent bonds are there between the two carbon atoms in butadiene?
Butadiene is H2C=C=CHCH3 ; This is one possible isomer. There are 11 covlanet bonds. H2C ' 2 C=C ' 2 C=C ' 2 CHCH3 ' 2 CH3 ' 3 So 2 + 2 + 2+ 2 + 3 = 11
Does the Lewis structure SO2 have resonance structure?
Sulfur dioxide has three resonance structures. A singly bonded oxygen would have 3 unshared electron pairs while a doubly bonded oxygen would have 2. The sulfur has one pair.
How many pi bonds and sigma bonds are in a molecule of 1 3 butadiene?
sigma bonds=9 and pi bonds=2
How many resonance structures does the nitrate ion NO2 -1 have?
3 structures
How many resonance structure can be drawn for ozone O3?
There are 2 resonance structures for ozone.
How many resonance structures does the nitrate ion NO21- have?
There are three possible, equally distributed, resonance structures of nitrate (NO3-).Cf. Related links for the possible Lewis structure of them, on the lowest half of that page.
Show how 1 4 diphenyl 1 3 butadiene might be synthesized from benzaldehyde and an appropriate halogenated compound?
Im not sure how to do this but I am trying to understand this process as well.
What are the products of the reaction of 1 3-butadiene with Br2 and H2O?
CH2=CH2-CH-CH2-Br 1-butene, 3- OH, 4-Br | OH Not sure but would be my best bet
What is the structure of NO2?
This ionic compound exists of two ions:ammonium, NH4+, is tetraedric (with H at 4 corners and N+ in centre)nitrate, NO3-, is trianular flat with N centred and O(1/3)- at 3 corners)The cristallic structure made of these ions (1 to 1) is trigonal. Nice pictures are at wikipedia, link is to be found at 'Related links' next to this answer, just clicking.[Ball-stick model, red = N, white = H, blue = N)
How many equivalent Lewis structures are necessary to describe the bonding in PO(OH)3?
In chemistry, resonance is a way of describing bonding in certain molecules or ions by the combination of several contributing structures (or forms, also variously known as resonance structures or canonical structures) into a resonance hybrid (or hybrid structure) in valence bond theory
What is the minimum number of moons that must be orbiting a planet for the moons to have an orbital resonance?
An orbital resonance occurs when one moon's orbital period is a simple fraction of the other's, such as 1/2 or 1/3 or 1/4, which means at least two moons are required.
How many resonance structures are there for CH3COO?
There are two possible resonance structures. These arise from the central carbon atom having a single covalent bond to one oxygen, and a double covalent bond to the other. The hydrogen-carbon bond is a single, and this doesn't change. The actual structure is a "blend" of the two possibilities, where the C-O bond length is equal; shorter than a single but longer than a double.
Does SO3 have a resonance structure?
Start with S on the middel for each one Put the 3 O on top bottom and side of S in each one one O is going to be doubel bonded and with two pairs of dots fore the other two just rotate
