  1. thanks for your valuable effort the mechanism seems to be correct. one thing i also wanted to know if u can clear my doubt, while drawing the resonating structures of chlorobenzene how can we show partial double bond character on chlorine though it cannot expand its octet?
  2. I am looking forward for the most plausible mechanism of the reaction between acid amide (derivative of carboxylic acid) and HNO2. although i know the general reaction ar written in my book ie. R-CONH2 + HNO2 == (HEAT) == >R-COOH + N2(evolved)+H2O mechanism would hel me identifying which kinds of acid amides and participate in such reactions.
  3. i am in high school and have just the preliminary knowledge of kinetics .I wanted to know in case of non uniform accelerated motion if velocity (in respect of time)is integrated to give displacement.if it turns out to be zero after solving.what is the method to find distance in such a case
  4. can please solve this although looks simple but i can't find my mistake An aircraft is flying at height of 3400m above the ground.If the angle subtended at a groung observation point by the aircraft positons 10secs apart is 30degrees ,what is the speed of the aircraft? tan30=10v\3400 well the ans i got is 196m/sec but actually the answer written is 182m/sec
  5. 21 men were employed to do a work in a cetain time.When 1/3rd of the time was completed only a quarter of work was done.How many more men should be employed to complete the work in 3/4th of the scheduled time. I got the answer as 11.(i am not sure)Can u help!! Jyoti
  6. Well Tejaswini , I hope u don't have read my question clearly. I Moreover , Its a forum where anyone can post about what she feels or wants to get it discussed. No matter, Koi Mil Gaya was really a nice movie and so is discovery channel , the programme "The amazing world of allen " Previously coming on Zee and much more stuff like that. Nothing to do with such programmes. Though meteorological department not have attended it, who knows what would happen the next day!! *I have not heard any voice to be true ( not just like in Koi Mil Gaya )!!
  7. Sorry for tuning in late but I have an answer to ur questions 1. Well You may be correct about the ordinary military jet but it cannot fly as near to the ground as I saw it. It is very difficult to not match it with a hot air balloon anyways. 2.Concerning its constant speed and the direction at night , there are 30% chances from my side to declare it as an UFO
  8. Well if it was an helicopter I must have heard some voice but there was no sound what so ever
  9. Well , there are very few chances that I can be right. I spotted an unidentified(according to me) object in the sky last night.It was 1. Flying very close to earth that I can easily view its design and structure. So It cannot be an aeroplane or rocket in a sense 2. Some may use illuminated kites, but it cannot be that because a total of three different lights were coming out of it .One red other green or yellow and the third was twinkling. 3.Moeover it was flying at a fairly constant speed I just wanted to know what are the speculations or statutory conditions to be declared it as an UFO and the other things for which I may have misinterpreted for it.
