Abstract: In this experiment the conversion of alcohols to alkyl halides are investigated through reflux and simple distillation. These are common procedures used to separate substances. After the reflux and distillation is complete 13C NMR and IR spectrum is used to identify the product or products for each reaction: 1a‚ 1b‚ and 2. Every individual in the group was assigned either 1a (1-propanol) or 1b (2-pentanol)‚ and 2 (1‚4-dimethyl-3-pentanol). The purpose of this experiment was to understand

Journal Entry1- Reducing Uncertainty Theory Uncertainty theory is an explanation of how we use information‚ as we strive to reduce our own uncertainty‚ in terms of how we relate to people‚ especially those people whom we do not know‚ or know very well. The communications theory creators Richard Calabrese‚ James Bradac‚ and Charles Berger believe that it is our motivation to reduce our own uncertainty‚ which drives us to communicate. We usually tend to respond to uncertainty in three ways: through

One out of every 88 children in the US is affected by an autism spectrum disorder. They occur more often among boys than girls. While autism appears to be on the rise‚ it’s unclear whether the growing number of diagnoses shows a real increase or comes from improved detection. Early diagnosis is important‚ as early treatment can help a child with autism make significant gains in language and social skills. Autism spectrum disorders affect social interaction‚ nonverbal and verbal communication‚ behaviors

deals with uncertainty reduction theory from its origin to date. Ever since uncertainty reduction theory was first created‚ many researchers have examined it by comparing it with other theories. Uncertainty reduction theory had been tested across different cultures in order to confirm its generalizability. It had also been applied to real life situations to examine how individuals interact in their initial encounters with strangers. In addition‚ researchers suggested testing uncertainty reduction

Meaning of Risk and Uncertainty Risk: In Common Parlance‚ risk means a low probability of an expected outcome. From business decision-making point of view‚ risk refers to a situation in which a business decision is expected to yield more than one outcome and the probability of each outcome is known to the decision makers or can be reliably estimated. For example‚ if a company doubles its advertisement expenditure‚ there are three probable outcomes: i) Its sales may more than double ii)

Define environmental uncertainty and resource dependence. Describe the major ways in which managers can deal with high environmental uncertainty and resource dependence. A good answer would base the analysis of environmental uncertainty on Duncan’s approach‚ which characterises uncertainty in the stable-unstable and simple-complex dimensions. It should identify buffering‚ boundary spanning‚ organisational differentiation and integration as responses to growing uncertainties. As to management of

Descartes’s Argument for Uncertainty 1. All previously held conceptions must be regarded as uncertain. a. Some previous conceptions were built on false opinions‚ or potentially false opinions and are therefore uncertain. b. All previous conceptions have been obtained from or through the senses‚ which guarantees their uncertainty. I. The senses have deceived in the past in cases of a small or distant thing‚ and could therefore do so again. II. The senses often deceive those who

The 2G spectrum scandal involved officials in the government of India illegally undercharging mobile telephony companies for frequency allocation licenses‚ which they would use to create 2G subscriptions for cell phones. The shortfall between the money collected and the money which the law mandated to be collected is 1‚76‚379 crore (1.763 trillion) rupees (roughly equivalent to 39 billion US dollars). The issuing of licenses occurred in 2008‚ but the scam came to public notice when the Indian Income

2G Spectrum Scam The Rs 1‚76‚000 crore loot in telecom by the UPA govt 1) What is spectrum? What is its relation with mobile phone services? Spectrum is airwaves. Each operator is assigned a set of frequencies. In normal basic telephone service‚ a pair of wires is used for communication. But in case of mobile/wireless communications‚ airwaves are used instead of wires. These spectrum/airwaves are licensed by the Government. It is allocated in Mega Hertz (MHz) in telecom licenses. 4.2 MHz is given
